Question

Which trinomial is a perfect square trinomial?

Answer 1

a y^2 + 6y + 36

b y^2 + 18y + 81

c y^2 + 50y + 100

d y^2 + 25y + 200

Answer 2

When it comes to polynomials like this and trying to figure out something like this, look at the second term and the last term and think about what two numbers multiplied together equal the last term, but also if you add together equals the middle term (second term)

Answer 3

A perfect square trinomial describes something like (x+2)^2. Where if we do the calculation, it would equal x^2 +2x +4
