Question

a^2-b^2-(a+b)^2 factorise​

Answer 1

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

HOPE THIS COULD HELP!!!

Answer 2

${a}^{2} - {b}^{2} - {( a+b )}^{2} \\ {a}^{2} - {b}^{2} - ( {a}^{2} + {b}^{2} + 2 \times a \times b) \\ {a}^{2} - {b}^{2} - {a}^{2} - {b}^{2} - 2ab \\ = - 2ab \\ may \: this \: answer \: helps \: you \:$
