8-12.

Factor each polynomial. Homework Help ✎

64

*x*^{2}–*y*^{2}12

*x*^{2}–*xy*– 6*y*^{2}4

*x*^{2}+ 12*x*+ 9*x*^{2}– 3*x*+ 18

This is a difference of squares.

(8*x* + *y*)(8*x* − *y*)

Use an area model and

a diamond problem to factor.

(4*x* − 3*y*)(3*x* + 2*y*)

This is a perfect square trinomial.

Can you find two numbers that

multiply to +18 and add to −3?
