Question

Find the product for (-2x²+xy-y²) (3x+4y)

Answer 1

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

$( - 2x {}^{2} + xy - y {}^{2} )(3x + 4y) \\ = - 2x {}^{2} (3x + 4y) + xy(3x + 4y) - y {}^{2} (3x + 4y) \\ = - 6x {}^{3} - 8x {}^{2} y + 3x {}^{2} y + 4xy {}^{2} - 3xy {}^{2} - 4y {}^{3} \\ = - 6x {}^{3} - 5x {}^{2} y + xy {}^{2} - 4y {}^{3}$
