Question

multiply z2/z+1.z2+3z+2/z2+3z

Answer 1

\[(\frac{ z^2 }{z+1 ? })(\frac{ z^2+3z+2 }{z^2+3z ? })\]

I want to make sure I am reading it correctly. Does it look like that (what I just typed)?

Answer 2

Well, except for the question marks - don't know how those got in there!

Answer 3

If so you could factor some of the expressions and then cancel the common factors out to simplify.

Answer 4

For example, z^2 + 3z = z(z + 3) and z^2 = z(z), so you could cancel out a z

Answer 5

So you can factor the expressions and do the multiplication, then check against this if that helps. :)

Answer 6

no ( ) or ? marks but yes
