Question

$Use the appropriate identity and find the product : (m + 5) ^{2}$
please till me please
​

Answer 1

(m + 5)² = m² + 10m + 25

Given :

The expression (m + 5)²

To find :

The product using suitable identity

Identity Used :

(a + b)² = a² + 2ab + b²

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is (m + 5)²

Step 2 of 2 :

Find the product

We are aware of the identity that

(a + b)² = a² + 2ab + b²

Thus we get ,

$\displaystyle \sf{ {(m + 5)}^{2} }$

$\displaystyle \sf{ = {(m)}^{2} + 2 \times m \times 5 + {(5)}^{2} }$

$\displaystyle \sf{ = {m}^{2} + 10m+ 25 }$
