Answer 2

(84).

$Given : \frac{a^3}{b - a} + \frac{b^3}{a - b}$

$= \ \textgreater \ \frac{a^3}{b - a} - \frac{b^3}{b - a}$

$= \ \textgreater \ \frac{a^3 - b^3}{b - a}$

$= \ \textgreater \ \frac{(a - b)(a^2 + ab + b^2)}{b - a}$

$= \ \textgreater \ - \frac{(a - b)(a^2 + ab + b^2)}{a - b}$

$= \ \textgreater \ -(a^2 + ab + b^2)$

$= \ \textgreater \ -a^2 - ab - b^2$


The answer is Option (B).



Hope this helps!
