Question

solve this plz its urgent​

Answer 1

$4x { }^{2} - y {}^{2}$

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

$= \: \: \: \: \: \: \: \: \: \: \: \: \: \: 4x {}^{2} - 2 \times 4x \times y + y {}^{2}$

$= \: \: \: \: \: \: \: \: \: \: \: \: \: \: 8x {}^{2} - 2 \times 4xy + y {}^{2}$

$= \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 6x {}^{2} \times 4xy + y {}^{2} \:$

$\\ ans = \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 24xy {}^{2} + y {}^{2}$
