Which is a factor of 15xy - 45x - 6y + 18?

xaze · Answer

It seems pretty easy but im not sure how to do it >n<

anonymous · Answer

15xy – 45x – 6y + 18 = 3 (5xy - 15x - 2y + 6) = 3 ( 5x(y - 3) - 2 (y - 3) ) = 3 (5x-2) (y - 3).

mrnood · Answer

look at all th terms separately

can you see a number which divides into all of them?

15xy
45x
6y
18

(hint - look at the last one first)

@MrNood, but the answers are shown as "5x-3" and "y-6" and stuff >.<

xaze · Answer

@joejoe213 Ah, my apologies, ma'am. ^^ Yes, I will fan you. xD

anonymous · Answer

its ok

xaze · Answer

So based on joejoe213's answer, 3 (5x-2) (y - 3), (5x-2) is one of the choices. So I believe (5x-2) is the correct answer.

mrnood · Answer

that is correct - but you didn't post the whole options.

3 is a factor as requested
