Q.242. - Intermediate Algebra

Question

Find the product of the below expression.

${\left(m+n\right)}^2$

Step-by-Step Solution

Answer

The solution is $m^2+2mn+n^2$.

Step 1. Given information.

The given expression is ${\left(m+n\right)}^2$.

Step 2. Simplify the given expression by using the binomial squares pattern a + b 2 = a 2 + 2 a b + b 2 .

Solve it as follows:

$$\begin{gathered} {\left(m+n\right)}^2={\left(m\right)}^2+2\times m\times n+{\left(n\right)}^2 \\ \Rightarrow m^2+2mn+n^2 \end{gathered}$$

Step 3. Simplified expression.

Hence, the required expression is $m^2+2mn+n^2$.
