Answer 1

Given,

$\sf{(a^2+2b)(a^2+2b)}$

We have to find the product here.

$\sf{\implies (a^2+2b)\times(a^2+2b)}$

$\sf{\implies (a^2\times a^2)+(a^2\times 2b)+ (2b \times a^2)+(2b\times 2b)}$

$\sf{\implies a^4+2a^2b+2a^2b+4b^2}$

$\sf{\implies a^4+4a^2b+4b^2}$

$\boxed{\bold{\sf{Answer= a^4+4a^2b+4b^2}}}$
