The Solve( command can be accessed in RUN mode by pressing the OPTN button.
In the screen that is then displayed are TABS (at the bottom).
Press [F4:CALC] then [F1:Solve]
The command echoes on the screen, ready to be completed and executed.

The variables you have at your disposal in this calculator are
A, B,C,D,X,Y,M. All of them are accessed by pressing the [ALPHA] key before the key near which is written the name of the variable. You will notice that the markings of the symbols accessed with the [ALPHA] key are of the same color as that of the [ALPHA] key.
You will notice also that there are two = signs.
The one at the bottom right executes the command line. By pressing it you find the result of the expression just entered.

The other = sign is marked on the body of the calculator with the same color as the [ALPHA] key. It is located at the top left of the keyboard (excluding the row with SHIFT, MODE, the navigation buttons)

Example to enter X^2-2X-35=0 (not your expression)
Direct access physical keys are in [ ],
[ALPHA] (X) [X to power 2] [ - ] [2] [ * ][ALPHA][(X) [ - ] [3][5] [ALPHA] (=) [0]

Usually when you enter such an expression it is with the intention of solving it for X. By default X is taken to be the UNKNOWN. You will be prompted to enter the value assigned to any other letter symbol (Y, A,B,C,D).

So, if you want to use the Solve function, you press [SHIFT] [CALC] and the calculator will ask you a question: "Solve for X?" , and you press the = sign at the bottom right.
Then you will be prompted for any other non-X letter.

You can do it the same way people did it before calculators were invented. Just use the quadratic formula: http://en.wikipedia.org/wiki/Quadratic_formula. Some sophisticated calculators have generalized equation solvers that can handle equations much more complicated than the quadratic, but the fx-82 isn't one of them.

### Factor quadratic equations

The calculator cannot do symbolic algebra. If equation is aX^2+bX+c=0, write it in the form a(X^2+(b/a)X+(c/a))=0 and solve the quadratic equation X^2+(b/a)X+(c/a)=0. Get the approximate roots X1, and X2 (if they exist) and write your original equation in the for
a(X-X1)(X-X2)=0
Your quadratic polynomial is factored as a(X-X1)(X-X2)

### I want to solve an complex equation on casio fx-570 ES Plus

Your scientific calculator is unable to solve complex equation with complex coefficients. You should try to solve by hand directly using the quadratic formula or by factoring the polynomial in z
failing that, another way would be to set z=x+iy, substitute this for z, carry out the algebra and try to separate real and imaginary parts. But your two equations will constitute a system of two quadratic equations. I am not aware of any general method to solve coupled nonlinear equations.
Good luck.

### How do i factor

This calculator is unable to factor a polynomial expression.
In general there are a few factoring methods
1. Factor by grouping terms
2. Factor by completing the square (quadratic polynomial)
3. Factor by finding two integers such their sum is equal to the coefficient of the middle term, and their product is equal to the third (constant term). This is valid for a quadratic polynomial where the leading coefficient (of the x^2 term) is equal to 1. X^2+SX+P
A cubic equation can be solved algebraically, although two solutions may be complex. Use the Cardano formulas. A quartic equation can be solved by the formulas for the quadratic equation, if you transform the quartic equation to look like A(X^2)^2 + B(X^2) +C=0

### Can you factor quadratic equations on the Casio fx-11ES? If yes how?

Press MODE 5 to bring up the equation types. Press 3 for the quadratic. Enter the three coefficients. Press = to see the first root. If the display shows x1 then press down to see the other other root. If the display only shows x then that's a double root. Given the two roots x1 and x2, the factors of the quadratic are (x-x1) and (x-x2).

Refer to "Equation Calculations" on page E-55 of the manual and examples #094 and #095 in the appendix for examples of solving quadratic equations. If the you need the manual and/or appendix, you can download them from
