Question

(1 + a-b/a+b) multiplied by (a/a^2+2ab+b^2)

Answer 1

The first term in parenthasis simplifies to 2a/(a+b); the second simplifies to a/[(a+b)^2].
Therefore, the product is 2a^2/(a+b)^3

Answer 2

(1 + a-b/a+b)=2a / (a+b)
(a/a^2+2ab+b^2)=a / (a+b)^2
(1 + a-b/a+b)*(a/a^2+2ab+b^2)=2a / (a+b) * a / (a+b)^2 =(2a^2) / (a+b)^3

Answer 3

(1 + a-b/a+b)*(a/a^2+2ab+b^2)
is it a-(b/a)+b or ((a-b)/a)+b or a-(b/(a+b)) or (a-b)/(a+b)?
it makes a big difference so put your brackets in place.
