Answer: The answer is C
Step-by-step explanation:
Well, an example of a perfect square trinomial would look like is:
[tex]a^2-2ab+b^2[/tex] or [tex]a^2+2ab+b^2[/tex]
So since we already know what [tex]a^2[/tex] is and what [tex]2ab[/tex] is we just have to find [tex]b^2[/tex]
However, we would use the [tex]a^2-2ab+b^2[/tex] formula to solve this since we have a subtraction sign
