Apply zero product theorem to solve for x[tex]x ^{2} = 9[/tex]

Sagot :

Answer:

[tex]\begin{gathered} x_1=-3 \\ x_2=3 \end{gathered}[/tex]

Step-by-step explanation:

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

[tex]x^2-9=0[/tex]

Factoring the binomial:

[tex]\begin{gathered} (x+3)(x-3)=0 \\ x_1+3=0 \\ x_1=-3 \\ \\ x_2-3=0 \\ x_2=3 \end{gathered}[/tex]
