But this can be simplified further @lalaly 

$\Large \color{MidnightBlue}{\Rightarrow (a + b)(a - b)(a^2 + b^2) }$

lalaly · Answer

yeah but u dont have to since its divided by (a^2-b^2) "check the question"

parthkohli · Answer

Oh yes.

anonymous · Answer

But the book answer is only (a^2+b^2) this is for lalaly to plz re-check .

lalaly · Answer

yeah i didnt give u the last answer,, i just showd  u another way of writing the numerator so it can be easier for u to figure it out... YOU recheck my post

lalaly · Answer

i didnt divide yet ,, when u divide, (a^2-b^2) on the top cancels with (a^2-b^2) in the bottom ,,, so u are left with (a^2+b^2)
