can someone please help me factor this problem 25-4v2?

25-4v^2
=(5+2v^2)(5-2v^2) answer//

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

25 - 4v^2
= 5^2 - (2v)^2
= (5 + 4v)(5 - 4v)

(5-2v)(5+2v)

25 - 4 v ² = ( 5 - 2 v ) ( 5 + 2 v )

25 - 4v^2

Difference of squares: (a + b)(a - b) = a^2 - ab + ab - b^2 = a^2 - b^2

Here a = 5, b = 2v

(5 + 2v)(5 - 2v)
