w^2-2w-3/w^2-2w+1 * w-1/w-3 multiply and simplify

Question

w^2-2w-3/w^2-2w+1  *  w-1/w-3   multiply and simplify

anonymous · Answer

=(w-3)(w+1)/(w-1)^2  *(w-1)/(w-3)
cancel out (w-1) & (w-3)

anonymous · Answer

=(w+1)/(w-1)

anonymous · Answer

Once you multiply you get
(w^3-2w^2-3w-w^2+2w+3)/(w^3-2w^2+w-3w^2+6w-3) Then combine like terms to get
(w^3-3w^2-w+3)/(w^3-5w^2+7w-3)

Pfft inik did it the easier way....why you so good!? XD

anonymous · Answer

i'm lazy... hate long multiplications :)

anonymous · Answer

XD My pre-cal teacher does a bunch of the long way ones, he's evil.

anonymous · Answer

said answer was wrong

anonymous · Answer

oups!
let's check!

anonymous · Answer

nope... still getting:
(w+1)/(w-1)

did you check original problem?

anonymous · Answer

it's (w+1) divide by (w-1)...
please check again.  I do not see any mistakes

anonymous · Answer

it wanted w-1/w-3

anonymous · Answer

how?
did you see the solution above?
w^2-2w-3=(w-3)(w+1)

so, you have to have (w+1) in answer...
can't get it. check with your teacher... something is wrong
