8-71.

For each equation below, solve for

*x*. Homework Help ✎(

*x*− 2)(*x*+ 8) = 0(3

*x*− 9)(*x*− 1) = 0(

*x*+ 10)(2*x*− 5) = 0(

*x*− 7)^{2}= 0

In order for a product to be 0, one of the factors must be equal to 0.

*x* − 2 = 0 or *x* + 8 = 0

Follow the steps in part (a).

*x* = 3 or 1

Follow the steps in part (b).

( *x* − 7 )^{2} = ( *x* − 7 )( *x* − 7 )

Follow the steps in part (a).
