Question

Use suitable special product to find : (m+7)(m-5). ​

Answer 1

Answer:

The given binomials are (2m+3) and (2m+3)

Their product will be (2m+3)(2m+3)

Using the identity, (a+b)(a+b)=a

2

+2ab+b

2

For the above expression, keeping a=2m and b=3, we get:

(2m+3)(2m+3)=4m

2

+12m+9

Hence, the product of the given binomials is 4m

2

+12m+9.
