Que :- (1/2 a-1/5 b) (1/2a²-1/3b²) ; a=2 and b=-4

Ans :- If a = 2 and b = -4

$( \frac{1}{2} a - \frac{1}{5} b)( \frac{1}{2} {a}^{2} - \frac{1}{3} {b}^{2} )$

$( \frac{1}{2}(2) - \frac{1}{5} ( - 4))( \frac{1}{2} {(2)}^{2} - \frac{1}{3} ( { - 4)}^{2}$

$(1 + \frac{4}{5} )(2 + \frac{16}{3} )$

$( \frac{5 + 4}{5} )( \frac{6 + 16}{3} )$

$( \frac{9}{5} )( \frac{22}{3} )$

$\frac{198}{15}$

$\frac{66}{5}$
