To solve, first add 4 to both sides of the equation. X^2–4+4=0+4. You then have x^2=4. Next, take the square root of both sides, which leaves x=2.

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.

You can solve any quadratic equation by completing the square—rewriting part of the equation as a perfect square trinomial. If you complete the square on the generic equation ax2 + bx + c = 0 and then solve for x, you find that .

['You can “manually” solve the equation on the calculator, meaning that if you want to solve the equation ax^2 + bx + c, you basically plug in the quadratic formula into the calculator and hit enter. ... ', 'The second way is faster, but be sure to check that your teacher is okay with you using it.']

We can find the solutions, or roots, of quadratic equations by setting one side equal to zero, factoring the polynomial, and then applying the Zero Product Property. The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0.

We will learn the formation of the quadratic equation whose roots are given. To form a quadratic equation, let α and β be the two roots. Let us assume that the required equation be ax2 + bx + c = 0 (a ≠ 0). According to the problem, roots of this equation are α and β.

A quadratic equation contains terms up to . There are many ways to solve quadratics. All quadratic equations can be written in the form a x 2 + b x + c = 0 where , and are numbers ( cannot be equal to 0, but and can be).

Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring.
