Answer

$x_1=4,\:x_2=2$

Step-by-step explanation

Problem to solve:

$x^2-6x+8=0$
1

To find the roots of a polynomial of the form $ax^2+bx+c$ we use the quadratic formula, where $a=1$, $b=-6$ and $c=8$

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

Substituting the values of the coefficients of the equation in the quadratic formula

$x=\frac{6\pm 2}{2}$
