What is factoring and give the examples


Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

Hi there,

My name is adieh.have a great day.

I will give a simple example on how to convert your answer into decimal form. Indicated below:

Q: Simplify 1/2-5/13 convert to decimal

Answer:

Step 1: Enter 1/2 by pressing 1>a/b>2.
Step 2: Subtract by pressing - (negative sign or minus sign)
Step 3: Enter 5/13 by pressing 5>a/b>13.
Step 4: Find the difference by pressing = (equals sign)
Step5: Convert to decimal by pressing (change)
You can find( change) on the right side of your calculator beside M+ key

I am suggesting you to visit this website http://files.sharpusa.com/Downloads/ForHome/HomeOffice/Calculators/Manuals/Archive/cal_man_ELW535B_TeachersGuide.pdf

Our t84 won't hold any battery life. we have changed both the lithium and the tripl a's and you can only use the calculator one and then its out of battery......what is going on?


Possibility: Some third-Party programs (games essentially) are installed on the calculator. They may be ill-designed and circumvent/turn OFF the Power saving features of the calcuator.Also, Texas Instruments recommends to use alkaline (non-rechargeable) batteries only.

How do i get rid of shadeRes in my window T84


You might have activated the application called Inequalz. It solves inequations. One of its feature is the shading of solution regions and the resolution of the shading is called ShadeRes. When you press the Window function key you see the ShadeRes value before the usual window dimensions.

To get rid of the Inequalz application (kick it out of memory without removing it completely from calculator)
  1. press the Apps key.
  2. Use downArrow to put focus on Inequalz and press ENTER
  3. In the new screen that is displayed "INEQUAL RUNNING" select [2:Quit Inequal].

T84


I always opened a new progam and typed whatever text, formulas, etc. I wanted to pull back up later. When you open your program option you will pull up what you typed in. This is a good way to organize information.

My Ti83 silver edition will not turn on.


I'm not sure if this will help you patchesb7; it sounds like your calculator is having issues :(
This will help others whose calculators suddenly won't turn on anymore, even after changing the batteries.

Note:
This will return the calculator to the way it was when you got it out of the package. Any data or programs have stored since will be lost.

Step 1: Remove all four AAA batteries.

Note: You will have to hold down the CLEAR button while doing Steps 2 and 3. Do not let go until after you have pushed ON in Step 3. I found this easiest to do by holding the calculator upside in my left hand with my pointer finger holding the CLEAR button so the ON button was easier to access.

Step 2: Hold down the CLEAR button (located under the arrow keys) and reinstall the AAA batteries.

Step 3: Press ON button and then let go of both buttons. The screen should say the RAM has been cleared. Press CLEAR to continue.

Batteries:
Make sure to replace the "battery backup" too the little lithium ion battery

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Hope that helps!
