Question

I have no idea what this means...

Answer 1

A = 1 and B = 10

It's in the form ax^2 + bx + c

Answer 2

It's saying that the polynomial can be factored into a perfect square (x + 5)(x+5) because when you multiply it, you get x² + 5x + 5x + 25 or x² + 10x + 25 so the factored form can be rewritten as (x + 5)² because it can be multiplied by itself to get the polynomial listed, so a = x and b = 5
