Question

Factorize: (a+b)-(a + b)²​

Answer 1

Answer:

(a+b)(1-a-b)

Step-by-step explanation:

(a+b)-(a+b)^2

=(a+b){1-(a+b)}

=(a+b)(1-a-b)

Answer 2

Answer:

Step-by-step explanation:

(a+b)-(a+b)*2

(a+b)-(a*2+2 ab+b*2)

(a+b)-a*2-2 ab-b*2

a(-a*2-2 ab-b*2)+b(-a*2-2 ab-b*2)

-a*3-2 a*2 b-ab*2-ab*2-2 ab*2-b*3

-a*3-4a*2b-2 ab*2-b*3
