2-10.

Factor out (*x* + 2) from each expression, then simplify.

Think about this problem as factoring *w*^{2} – 3*w*, where *w* = *x* + 2.

(

*x*+ 2)^{2}− 3(*x*+ 2)(

*x*+ 2)((*x*+ 2) − 3)(

*x*+ 2)(*x*− 1)(

*x*+ 2)^{3}− 4(*x*+ 2)Follow the same process as (a) above.

2(

*x*+ 2)^{2}+ 6(*x*+ 2)Follow the same process as (a) above.
