Use the zero product property to find the solutions to the equation x2 – 9 = 16. x = –3 or x = 3 x
= –6 or x = –3 x
= –5 or x = 5 x
= 7 or x = 1

x^2-9=16

x^2=16+9

x^2=25

=±5

(-5 or 5)

Verification:

5^2-9=16

25-9=16

(-5)^2-9=16

25-9=16

i dont know what you want me to answer for this but im guessing 2: 11?
