Answer 1

Heya user !!

Here's the answer you are looking for
$\frac{ {a}^{3} }{b - a} + \frac{ {b}^{3} }{a - b} \\ \\ \frac{ - {a}^{3} }{a - b} + \frac{ {b}^{3} }{a - b} \\ \\ \frac{ {b}^{3} - {a}^{3} }{a - b} \\ \\ \frac{(b - a)( {b}^{2} + ab + {a}^{2} )}{(a - b)} \\ \\ \frac{ - (a - b)( {b}^{2} + ab + {a}^{2} )}{(a - b)} \\ \\ - ({b}^{2} + ab + {a}^{2} )$
