Question 146376
Reduce:
{{{highlight((a^2-b^2))(a+b)/(a+b)^2}}} Expand the indicated factor in the numerator.
{{{highlight((a+b)(a-b))(a+b)/(a+b)^2}}} Rearrange the numerator a bit.
{{{highlight((a+b)(a+b))(a-b)/(a+b)^2}}}={{{highlight((a+b)^2)(a-b)/(a+b)^2}}}
Cancel the common factors.
{{{(cross((a+b)^2)(a-b)/cross((a+b)^2))}}}={{{a-b}}}
