How would I multiply the following rational expression?

((m^2-1)/(m^2+1))*((m^4+2m^2+1)/(m-1))

Question

How would I multiply the following rational expression?

((m^2-1)/(m^2+1))*((m^4+2m^2+1)/(m-1))

anonymous · Answer

$$((m ^{2}-1)/(m ^{2}+1)) *((m ^{4}+2m ^{2}+1)/(m-1))$$

jhonyy9 · Answer

so there are

m^2 -1       m^4 +2m^2 +1
-------- * ---------------- =
m^2 +1              m-1

correct ?

anonymous · Answer

yup!

jhonyy9 · Answer

so how you see what is inside first parantheses ?

anonymous · Answer

(m-1)(m+1)

jhonyy9 · Answer

yes sure

jhonyy9 · Answer

and what is the second numerator

jhonyy9 · Answer

?

anonymous · Answer

(m+1)(m+1)

jhonyy9 · Answer

this is right too

anonymous · Answer

next bracket is (m-1)^2(m+1)^2/m-1

jhonyy9 · Answer

sorry but this how you have wrote i dont understand it

anonymous · Answer

((m-1)^2(m+1)^2)/(m-1)

jhonyy9 · Answer

why you have got this ?

anonymous · Answer

I dont know. Is the answer to the question (m-1)^2 (m+1) ?

jhonyy9 · Answer

so you have solved it step by step right than just you need to unit these steps together and will get the right result

anonymous · Answer

is (m-1)^2 (m+1) the correct answer?

jhonyy9 · Answer

(m-1)(m+1)    (m^2 +1)^2
---------- * ------------ = 
m^2 +1             m-1

came on just you need to simplifie it and will get the right result

jhonyy9 · Answer

courage please this is very easy
