Question

Match the missing term with the perfect square trinomial 9x^2 +?+25

that's false, thomas.

Answer 4

No it is not

Answer 5

30x

Answer 6

How so?

Answer 7

3*5*2

Answer 8

If it is a perfect square trinomial, then they both must begin with 3x (because 3x times 3x = 9x^2)
And they both must end with +5, as 5^2 = 25

So the binomials MUST be (3x+5)(3x+5)...now multiply to get your answer.
