How to solve using the quadratic formula
If you have a general quadratic equation like this: ax^2+bx+c=0 ax2 + bx + c = 0 Then the formula will help you find the roots of a quadratic equation, i.e. the values of x x where this equation is solved. The quadratic formula x=\dfrac {-b\pm\sqrt {b^2-4ac}} {2a} x = 2a−b ± b2 − 4ac It may look a little scary, but you’ll get used to it quickly! WebKeep in mind that even if you do everything correctly when solving a quadratic equation using the quadratic formula, you are not guaranteed to get real solutions. If a quadratic equation has no real solutions, that will be revealed regardless of how you solve the equation (completing the square, quadratic formula, etc.).
