Question

What is the product in simplest form? State any restrictions on the variable.

z^2/z + 1 times z^2 + 3z+2/z^2 + 3z

Answer 1

\[\frac{ z^2 }{ z + 1}\times \frac{ z^2 + 3z + 2 }{ z^2 + 3z }\]

Answer 2

@tcarroll010 how do you do this one ?

Answer 3

Answer 5

@cgreenwade2000 do you know how to do this !?

Answer 6

start by breaking down (x^2 + 3z + 2)

Answer 7

It's easier actually to just factor everything as much as possible and then reducing from there.

Answer 8

(x + 2)(x + 1) ?

Answer 9

Yes. Now factor z^2 and z^2+3z

Answer 10

um idk that

Answer 11

@cgreenwade2000

Answer 12

z^2 = z*?

Answer 13

and z^2 +3z = ?

There is something you can pull from those terms

Answer 14

z ?

Answer 15

yes so you can simplify z^2 to get z*z

what can you factor out of z^2 + 3z?

Answer 16

z(z +3) @cgreenwade2000

Answer 17

Yes.

Now rewrite your problem with your factored expressions in

Answer 18

z*z x (x + 2)(x + 1)/z(z +3) ? @cgreenwade2000

Answer 19

You put some x's in there. Be careful of that. There are no x variables in this problem
