Answer 1

Answer:

Hope it will help you

Step-by-step explanation:

(a+b) x (2a+b) + (a+ 2b) x (a-b)

2a²+ab+2ab+b² + a²-ab+2ab-2b²

2a²+a²+ab+2ab+2ab+b²-2b²

3a²+5ab-2b²

3a²+3ab+2ab-2b²

3a(a+b) + 2b(a+b)

(a+b) (3a+2b)

Thank you

Answer 2

Answer:

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

on multiplying we get

2a^2+a-b+2ab+b^2+a^2-ab+2ab-2b^2

+a-b and -a-b cancels

on solving we get

3a^2+4ab-b^2
