Question

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

Answer 1

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

Answer 2

Answer:

Option D  is correct.

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

Step-by-step 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, $4x^2-25y^2$
