If someone could help me with these last few problems, it would be nice. Check all polynomials that are perfect square trinomials: A) 49x^2 âˆ’ 8x + 16 B) 4a^2 âˆ’ 20a + 25 C) 25b^2 âˆ’ 5b + 10 D) 16x^2 âˆ’ 8x + 1
Which ones are perfect square trinomials?
a is do you know how i figured that out?
No, I don't.
have you learned foil?
No A is not the right answer!
Diya, there is more than one I can choose for the right answer. How come A isn't one of them?
