8-49.

Factor each polynomial. Homework Help ✎

*x*^{2}− 64*y*^{2}− 6*y*+ 94

*x*^{2}+ 4*x*+ 15

*x*^{2}− 45

This is a difference of two squares.

(*x* + 8)(*x* − 8)

This is a perfect square trinomial.

(*y* − 3)^{2}

Look at the hint in part (b).

Start by factoring out the greatest common factor. Then look at the hint in part (a).
