$x=2,10$

Let us re-write the equation in the standard form $x^2-12x+20=0$

Here, we are given a quadratic equation.
The standard form of a quadratic equation is $ax^2 + bx + c = 0$

This means the equation has 2 roots.

The quadratic formula to find the roots of the equation is

$x_(1,2)=(-b +-sqrt(b^2-4ac))/(2a)$

The step-by-step walk through to solving the equation is shown below.
