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 = -5 or x = 5

Step-by-step explanation:

we have the equation:

moving the 16 to the left of the equation

and we know that , so:

this is what is known as a difference of squares, which is equal to:

and using the zero property, wich tells us that if a product is equal to zero, each of the terms could be equal to zero:

→

or

→

The correct answer is x = -5 or x = 5
