Answer 2

$\huge\boxed{\texttt{\fcolorbox{Red}{aqua}{Hey friend!!}}}$

Here is your answer

$(4x - 3y) {}^{3} + (3x - 4y) {}^{3} \\ \\ = 64 {x}^{3} - 27 {y}^{3} - 144 {x}^{2} y + 108x {y}^{2} + 27 {x}^{3} - 64 {y}^{3} - 108 {x}^{2} y + 144x {y}^{2} \\ \\ = (64 + 27) {x}^{3} - (64 + 27) {y}^{3} - (144 + 108) {x}^{2} y + (108 + 144)x {y}^{2} \\ \\ = 91 {x}^{3} - 91 {y}^{3} - 252 {x}^{2} y + 252x {y}^{2}$
Hope it helps you
