Answer:
(x - 6)(x - 6)
Step-by-step explanation:
The given quadratic equation is [tex]$ x^2 - 12x + 36 = 0 $[/tex].
A quadratic equation can be factored in the form [tex]$ (x - a)(x - b) $[/tex] where [tex]$ -a $[/tex] and [tex]$ -b $[/tex] will form the roots of the equation.
Here the roots are: [tex]$ +6 , +6 $[/tex].
The factored form would simply be: [tex]$ (x - 6) (x - 6) $[/tex].
