Question

Help. Medal. :)

Check all polynomials that are perfect square trinomials:

9x^2 - 6x + 1
36b^2 - 24b + 8
16x^2 + 24x + 9
4a^2 - 10a + 25

Answer 1

hmmmmmmmm that ???????????????????

Answer 2

(a+b)^2=a^2+2ab+b^2
(a-b)^2=a^2-2ab+b^2

Answer 3

check if somebody fits that

Answer 4

Try factoring them using this law:\[(x+y)(x+y)=x ^{2}+2xy+y\]\[(x-y)(x-y)=x ^{2}-2xy+y\]

Answer 5

A C
