Hi nadiajesse

Question 1

First of all x is the alphabet x and 2 stands for square of a number

So 6x2 is read as "6 x square"

Answer for Question 1 is: (3x+1)(2x+3)

Answer for Question 2 is : (3x-2) (x-4)

If you are happy with the answer, please give a rating

Cheers

15 + 11x

14 + -14x

Next time use asterisks for multiplication symbols ***********************************************

or you will confuse many people

What is the question. Your calculator FX-9750 GII does not have a Computer Algebra System or CAS, so you cannot factor a polynomial.

If you want you can try to find the zeros of the polynomial function (the values of x when the function crosses the horizontal axis) either by solving P(x)=0 or by graphing y=P(x).

Once you have the approximate roots x_1, x_2, ...,x_n, you can factor out the coefficient of the leading term (the term with the highest power) and write P(x) =a_n *G(x). here a_n is the coefficient of the leading term.

G(x) can then be written as G(x)=(x-x_1)(x-x_2)*(x=x_3)...(x-x_n)

and the original polynomial will be

P(x)=a_n(x-x_1)(x-x_2)*...*(x-x_n)

Note: Here is an example of P(x) and the corresponding G(x)

P(x)=5x^3+7x^2-13x^+29

P(x)=5**(x^3+ (7/3)*x^2-(13/5)x+29/5)**

G(x)=**x^3+ (7/3)*x^2-(13/5)x+29/5**

You should keep in mind that the roots are in general complex. Not all polynomials are factorisable in the set of Real numbers.

Most calculators (except perhaps the TI89) can't do this sort of simplification, so you will need to factorise the number yourself to get sqr(200) = sqr(2*100) = sqr(2) * sqr(100) = sqr(2) * 10.

I would be interested in knowing the model number of the Casio calculator that can do prime factorization. I know and own several Casios (scientific and graphing) calculators and I have not found one that does it. Some graphing calculators are able to perform the factorization with the help of an additional program.

11^27 = 13,109,994,191,499,930,367,061,460,371 which is 29 digits long.

You can get this result from the Windows calculator (scientific view) by entering 11 and then pressing x^y 27 = . Then use Mod 29 = to get the result, which is 8.

Unfortunately the Casio fx-991ms (as with most other calculators) doesn't have nearly enough digits to cope with this type of calculation. You therefore need to split the calculation down into more manageable chunks, as follows, which works on most calculators:

First calculate 11^3 = 1,331 and work out Mod 29, which is 1,331 - 45×29 = 26.

Then calculate 26^3 = 17,576 and work out Mod 29, which is 17,576 - 606×29 = 2.

Finally calculate 2^3 = 8. Since this is less than 29, it is also the final answer as confirmed above.

This method can be used with any power number that can be factorised into numbers that don't cause the available digits of the display to overflow. In this case 27 = 3×3×3 so each step involves cubing the previous answer.

The answer is 98:

2 + 3 = 2 * ( 2 + 3 ) - 2 = 8

3 + 7 = 3 * ( 3 + 7 ) - 3 = 27

4 + 5 = 4 * ( 4 + 5 ) - 4 = 32

5 + 8 = 5 * ( 5 + 8 ) - 5 = 60

6 + 7 = 6 * ( 6 + 7 ) - 6 = 72

7 + 8 = 7 * ( 7 + 8 ) - 7 = 98

2 + 3 = 2 * ( 2 + 3 ) - 2 = 8

3 + 7 = 3 * ( 3 + 7 ) - 3 = 27

4 + 5 = 4 * ( 4 + 5 ) - 4 = 32

5 + 8 = 5 * ( 5 + 8 ) - 5 = 60

6 + 7 = 6 * ( 6 + 7 ) - 6 = 72

7 + 8 = 7 * ( 7 + 8 ) - 7 = 98

I am somewhat puzzled at your affirmation concerning factoring and expanding algebraic expressions. The TINspire does not do symbolic algebra, only the TI Nspire CAS does.

If you have the TINspire CAS, (version 2.x) you can

If you have the TINspire CAS, (version 2.x) you can

- press the HOME button, then select A:Calculate.
- In one of the pages, press MENU.
- Select [3:Algebra]
- Use Down Arrow or enter the number 2:Factor, or 3:expand
- In the command line, expand( , complete the command by entering the expression, close the right parenthesis and press [ENTER].
- The calculator should give you the expanded result.
