Answer

{$8,12$}

Work Step by Step

Using the rules of factoring trinomials to factor the polynomial, we obtain: $x^{2}-20x+96=0$ $x^{2}-8x-12x+96=0$ $x(x-8)-12(x-8)=0$ $(x-8)(x-12)=0$ Now, we equate the two factors to zero and solve: $(x-8)(x-12)=0$ $(x-8)=0$ or $(x-12)=0$ $x=8$ or $x=12$ Therefore, the solution set is {$8,12$}.
