What is a Quadratic Equation?

A quadratic equation is what can be written in the form of ax²+bx+c=0

The quadratic equation is

x² -10x = -34

x² -10x+34 = 0

The roots of the quadratic equation will be determined by the formula

$\rm x = \dfrac{-b \pm \sqrt{b^2- 4ac}}{2a}$

Here a = 1

b = -10

c = 34

$\rm x = \dfrac{10 \pm \sqrt{(-10)^2- 4*34*1}}{2*1}$

$\rm x = \dfrac{ 10 \pm \sqrt{-36}}{2}$

x = 5 $\rm \pm$ 3i
