Question

Identify the factors of x^2 + 36y^2.

Prime
(x + 6y)(x - 6y)
(x + 6y)(x + 6y)
(x - 6y)(x - 6y)

Answer 1

I think it's A, but im not sure :(

Answer 2

I feel like it could be B to.. because can't you factor 36 by 6?

Answer 3

Any ideas anyone?:L

Answer 4

\[(x-6 i y) (x+6 i y)=x^2+36 y^2 \]

Answer 5

So B? @robtobey

Answer 6

Your answer choices are all wrong. Along with the question itself.

Answer 7

That's what my homework gave me tho? .-.

Answer 8

I'm pretty sure its B because of the formula you have to use.. a^2 - b^2 = (a + b)(a- b)

Answer 9

\[x^2+36y^2 \implies (x)^2+(6y)^2\implies ?\]x and 36y\(^2\) are perfect squares. You just need to find their base.

Answer 10

b. is \[x^2+12 x y+36 y^2 \]

Answer 11

So if none of the answering are up there it's prime?

Answer 12

In the sense that it cannot be factored to give real numbers, yes.

Answer 13

Thank you! @robtobey :)

Answer 14

Your welcome and thank you for the medal.
