Question

Find the product of (2x + 5y)(2x − 5y).

4x2 − 20xy + 25y2
4x2 + 20xy + 25y2
4x2 + 25y2
4x2 − 25y2

Answer 1

The final answer for this is 4x^2-25y^2.

Answer 2

Option D is correct.

the product of
`(2x+5y)(2x-5y)` is,
`4x^2-25y^2`

Explanation:

Using identity rule:

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

To find the product of:

`(2x+5y)(2x-5y)`

Apply the identity rule:

here, a = 2x and b = 5y then

`(2x+5y)(2x-5y) =(2x)^2-(5y)^2`

=
`4x^2-25y^2`

Therefore, the product of
`(2x+5y)(2x-5y)` is,
`4x^2-25y^2`
