[tex] a^{2} - b^{2} =(a+b)(a-b) \\ 4x2 - 0x - 25 = 4x2- 25=(2x+5)(2x-5)[/tex]

Answer:

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

Step-by-step explanation:

Given : [tex]4x^2 - 0x - 25[/tex]

Solution:

[tex]4x^2 - 0x - 25[/tex]

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

So,It can be written as  [tex](2x)^2 - (5)^2[/tex]

Now using identity : [tex]a^2-b^2=(a+b)(a-b)[/tex]

[tex](2x)^2 - (5)^2[/tex]

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

So, the correct factorization of this trinomial is [tex](2x-5)(2x+5)[/tex]

Hence Option B is true.
