## Examples of diferent forms of quadratic equations

Solving a quadratic equation means finding all values of x that satisfy the equation.

It is very easy to solve quadratic equations, as long as they are having the form

If that's not the case, you will have to rewrite the equation, so that it has the same form as the equation above.

Rewriting the equation:

The same value can be added on both sides of the equation

The same value can be subtracted on both sides of the equation

You can multiply by the same value on both sides of the equation (except 0)

You can divide by the same value on both sides of the equation (except 0)
