Starting from your calculator home screen, press the [PRGM] button. Select the Quadratic Formula Program from the list, and press the [ENTER] button to run it. The program will prompt you to enter the coefficients a, b, and c. After providing these to the program, it will display the solutions on the screen!

Complete the square of ax2 + bx + c = 0 to arrive at the Quadratic Formula. Divide both sides of the equation by a, so that the coefficient of x2 is 1. Rewrite so the left side is in form x2 + bx (although in this case bx is actually ). Since the coefficient on x is , the value to add to both sides is .

Begin by multiplying both sides by the LCD, x(x+1) x ( x + 1 ) . After distributing and dividing out the common factors, a quadratic equation remains. To solve it, rewrite it in standard form, factor, and then set each factor equal to 0. Check to see if these values solve the original equation.

Where a, b, and c are constants and a ≠ 0. In other words there must be a x2 term. One way to solve a quadratic equation is by factoring the trinomial.

Don't be fooled: Not all quadratic equations can be solved by factoring. For example, x2 - 3x = 3 is not solvable with this method. One way to solve quadratic equations is by completing the square; still another method is to graph the solution (a quadratic graph forms a parabola—a U-shaped line seen on the graph).

The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.

The first step is to write the equation as quadratic = linear. Then you just take all values to one side so that you remain with 0 on the other. Next solve the quadratic equation so that you end up with the possible values of x.

The Quadratic Formula can be used to solve any quadratic equation of the form ax2 + bx + c = 0. The form ax2 + bx + c = 0 is called standard form of a quadratic equation.
