Question

Find the length of the side of the square
9x^2 + 6x + 1

Answer 1

i assume that is the area?

Answer 2

Try factoring that.

Answer 3

factor it then get the square root

Answer 4

Yes the area

Answer 5

\[\Large s=\sqrt A=\sqrt{9x^2+6x+1}=\sqrt{(\cdots)^2}=\cdots\]

Answer 6

I'm still not getting it?

Answer 7

Factor your polynomial like I suggested, and the answer will become obvious.

Answer 8

(3x+3) (3x-2) ?

Answer 9

I don't think I am factoring it correctly?

Answer 10

That's not correct...you can see that by FOILing that expression and seeing that it doesn't match the original. Try again.

Answer 11

Hint: the two factors will be equal. (This is why it's a square)

Answer 12

So when you multiple them they equal 6 and when added they equal 1 ?
