### How do I get all the factors of a constant using my calculator?

There is a program on page 253 of the manual (http://support.casio.com/manualfile.php?rgn=5&cid=004002013) to get the prime factors of any number. You could modify the program to get all the factors.

Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example:

120 /1 = 120 thus factor is (1, 120)
120/2 = 60 thus factor is (2, 60)
120/3 = 40 thus factor is (3, 40)
120/4 = 30 thus factor is (4, 30)
120/5 = 24 thus factor is (5, 24)
120/6 = 20 thus factor is (6, 20)
120/7 = 1.7 thus 7 not a factor
120/8 = 15 thus factor is (8,15)
120/9 = 13.3 thus 9 is not a factor
120/10 = 12 thus factor is (10,12)
120/11 = 10.9 thus 11 is not a factor.

Good luck.

### Need instruction how to solve ploynomials/trinomials

You can do it two ways.
Graphically:
Open the graph utility, enter a function y1= expression(x) where expression(x) is the polynomial. Graph the function y1(x). Play with the window dimensions to display the interesting part of the graph. You can then see if there are any zeros (roots).
While the graph is displayed, press SHIFT F5 (G-Solv). Press F1:Root to look for a root. Read the value of the root at the bottom of the screen (to the left).

Solve utility
Open the QEquation solver, select F2:polynomial, or F3: solver.
The polynomial solve can solve polynomial equations up to degree 6.
The solve solve polynomial and any other type of non algebraic equations

1. Most graphing calculators basically function the same way.
2. You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
3. You enter the algebraic form of the function you want to draw.
4. You press a button or menu to GRAPH
5. The graph is drawn.
6. If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
7. Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
8. You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.
