8-71.

For each equation below, solve for $x$.

1.  $(x-2)(x+8)=0$

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

$x-2=0$ or $x+8=0$

1.  $(3x-9)(x-1)=0$

Follow the steps in part (a).

$x=3$ or $1$

1.  $(x+10)(2x-5)=0$

Follow the steps in part (a).

1.  $(x-7)^2=0$

$(x-7)^2=(x-7)(x-7)$

Follow the steps in part (a).
