I'm not sure if I know how to write these out, but here goes: (multiply and simplify)

k^2+11k+28Xk^2+8k

k^2+12k+32Xk^2+4k-21

ADD and simplify:

m^2-8m+15

m-5 m-5

That is m^2-8m over m-5 PLUS

15 over m-5

The first one (k^2+11k+28)(k^2+8k)=k^4+8k^3+11k^3+88k^2+28k^2+22 4k=k^4+19k^3+116k^2+224k

That looks like it to me unless I messed up my mental math. Do you see the method? - Sep 13th 2006, 08:05 PMSuwanee
