Answer:

Option D  is correct.

the product of [tex](2x+5y)(2x-5y)[/tex] is, [tex]4x^2-25y^2[/tex]

Step-by-step explanation:

Using identity rule:

[tex](a+b)(a-b) = a^2-b^2[/tex]

To find the product of:

[tex](2x+5y)(2x-5y)[/tex]

Apply the identity rule:

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

[tex](2x+5y)(2x-5y) =(2x)^2-(5y)^2[/tex]

=[tex]4x^2-25y^2[/tex]

Therefore, the product of [tex](2x+5y)(2x-5y)[/tex] is, [tex]4x^2-25y^2[/tex]
