Question

A^2-2(a+b)-b^2. plzz help plzz solve this factorization plzzzzzz​

Answer 1

`\displaystyle\bf \star a^2-b^2=(a-b)(a+b)\star\\\\ a^2-2(a+b)-b^2=a^2-b^2-2(a+b)=\\\\\underline{(a+b)}(a-b)-2\underline{(a+b)}=\boxed{(a+b)(a-b-2)}`

Answer 2

Explanation:

a² -2(a+b) - b² = a² - 2a - 2b -b²

= a² - b² - 2a - 2b

= (a+b)(a-b) - 2 (a+b)

= (a+b)(a - b - 2)
