Answer:
Answer C
[tex]\Large \boxed{\sf \bf \ \ (5x-4)(5x+4) \ \ }[/tex]
Step-by-step explanation:
Hello, I assume that you means [tex]25x^2-16[/tex], right?
[tex]25x^2-16=(5x)^2-4^2=\large \boxed{\sf (5x-4)(5x+4)}[/tex]
Because we know that a and b real numbers:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
