Question

The polynomial below is a perfect square trinomial of the form:
A^2 - 2AB + B^2

True or False

9x^2 - 18x + 36

Answer 1

if we take square roots of 9x^2 and 36 we get 3x and - 6

so if we write
(3x - 6)(3x - 6)
does that expand to 9x^2 - 18x + 36?

Answer 2

thank you!!
i understand it now!

Answer 3

yw

Answer 4

as you see the middle term would come to -6*3x - 6*3x = -36x not -18x
