Question

T
Using identity the product of (3m+2)(3m+5)​

Answer 1

Answer:

We need to multiply the polynomials (2l−3m)(2l+3m)

By using identity (a+b)(a−b)=a

2

−b

2

, we can find the product.

Here a=2l,b=3m

Therefore, (2l−3m)(2l+3m)=4l

2

−9m

2

This is the required answer.

Answer 2

3m(3m+5)+2(3m+5)

=9m2+15m+6m+10

=9m2+21m+10
