Question

Is y(x-9) over x^2-9 already simplified? Can it not be simplified anymore? Answer me, please.

Answer 1

remember that you can factor out x^2 - 9 further..do you know how to factor out difference of two squares?

Answer 2

I don't know @lgbasallote

Answer 3

Hint: \((a+b)(a-b) = a^2 - b^2\)

that give you any ideas?

Answer 4

Yeah

Answer 5

good! so how can you factor out \(x^2 - 9^2\)

Answer 6

The answer would be \[3y \over x+3\]. Am I right?

Answer 7

hey wait...it's \(\frac {y(x-9)}{x^2 - 9}\)?

Answer 8

Yeah

Answer 9

well this is embarassing....i got ahead of myself..it cannot be simplified further..forgive me <tips imaginary hat>

Answer 10

Ah. Ok. Thanks a lot

Answer 11

Answer 12

It's fine. It's good that I'm learning :) I actually thought it can still be simplified and came up with an answer. Haha
