# Simplify: A2b2(A + 2b)(3a + B) - Mathematics

Simplify:
a2b2(a + 2b)(3a + b)

#### Solution

To simplify, we will proceed as follows:

$a^2 b^2 \left( a + 2b \right)\left( 3a + b \right)$

$= \left[ a^2 b^2 \left( a + 2b \right) \right]\left( 3a + b \right)$

$= \left( a^3 b^2 + 2 a^2 b^3 \right)\left( 3a + b \right)$

$= 3a\left( a^3 b^2 + 2 a^2 b^3 \right) + b\left( a^3 b^2 + 2 a^2 b^3 \right)$

$= 3 a^4 b^2 + 6 a^3 b^3 + a^3 b^3 + 2 a^2 b^4$

$= 3 a^4 b^2 + 7 a^3 b^3 + 2 a^2 b^4$

Thus, the answer is $3 a^4 b^2 + 7 a^3 b^3 + 2 a^2 b^4$ .
