Answer 2

SOLUTION

TO EXPAND

$\sf{ {(m + 2n)}^{2} }$

EVALUATION

We have to expand the expression

$\sf{ {(m + 2n)}^{2} }$

We are aware of the formula that

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

Let us take a = m and b = 2n

Then we have

$\sf{ {(m + 2n)}^{2} }$

$\sf{ = {(m)}^{2} + 2 \times m \times 2n + {(2n)}^{2} }$

$\sf{ = {m}^{2} + 4mn + 4 {n}^{2} }$
