Answer 2

@texaschic101

Answer 3

I'm pretty sure that to create a perfect square trinomial you divide the middle term by 2, square it, and then add it to the expression so it is the 3rd term

Answer 4

@RiOT so to square 4w it would be 4w^2

Answer 5

what about this did i do this right?

Answer 6

sorry, just the coefficent, so it would be 4^2

Answer 7
