Answer:

#x=2,10#

Explanation:

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.
