Question

Apply zero product theorem to solve for x$x ^{2} = 9$

Answer 1

Answer:

$\begin{gathered} x_1=-3 \\ x_2=3 \end{gathered}$

Step-by-step explanation:

To apply the zero product theorem, put all the terms on the left side to equal zero.

$x^2-9=0$

Factoring the binomial:

$\begin{gathered} (x+3)(x-3)=0 \\ x_1+3=0 \\ x_1=-3 \\ \\ x_2-3=0 \\ x_2=3 \end{gathered}$
