Question

Find the product of (4x + 3y)(4x − 3y).

16x2 − 24xy + 9y2
16x2 − 9y2
16x2 + 24xy + 9y2
16x2 + 9y2

Answer 1

It's B

Explanation:

B, 16x2-9y2

Answer 2

Answer: The correct option is (B)
`16x^2-9y^2.`

Step-by-step explanation: We are given to find the following product :

`P=(4x+3y)(4x-3y)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

To find the given product, we will be using the following formula :

`(a+b)(a-b)=a^2-b^2.`

The product (i) can be calculated as follows :

`P\\\\=(4x+3y)(4x-3y)\\\\=(4x)^2-(3y)^2\\\\=16x^2-9y^2.`

Thus, the required product is
`16x^2-9y^2.`

Option (B) is CORRECT.
