Question

Medal for best answer!!!



Select the polynomial that is a perfect square trinomial.


9x2 + 9x + 1

36b2 − 24b + 8

16x2 + 24x + 9

4a2 − 10a + 25

Answer 1

try factoring them

Answer 2

It's either 1st or 3rd

Answer 3

Both 1st and 3rd end up to be the middle number

Answer 4

@tkhunny

Answer 5

Hint the first and last terms will be perfect squares
- and the middle number must fit in as you said

Answer 6

you are right its either 1 or 3

Answer 7

They both qualify I don't know which one is better

Answer 8

no if you try factorinbg them you'[ll see which is the right one

Answer 9

Idk how to factor

Answer 10

9x^2 ~ 9x + 1

sqrt 9x^2 = 3x and sqrt 1 = 1
so lets write
(3x + 1)(3x + 1)


does that expand to 9x^2 + 9x + 1?

Answer 11

Yes

Answer 12

(3x + 1)(3x + 1)
= 3x(3x + 1) + 1(3x + 1)
can you continue?

Answer 13

= 9x^2 + 3x + 3x + 1

Answer 14

- it does not...
]'the middle term is 6x

Answer 15

Okay so the answer is the 1st one?

Answer 16

NO!! because (3x + 1)^2 is not = first one - its not a perfect square

Answer 17

3rd one?

Answer 18

yes

9X62 + 6x + 1 is a perfect square but 9x^2 + 9x + 1 is

Answer 19

do you understand the reasoning?

Answer 20

Yes I have one more that I am not sure can you check it?

Answer 21

Given the following perfect square trinomial, fill in the missing term.

x2 − 16x +

Answer 22

please post it separately

Answer 23

Okay I will tag you
