Factoring polynomials?

Question

I amj really confuse and stuck on factoring this polynomial please show step by step work

6) 2x2y - 4xy - 30y

Answer 1

take out a common factor, 2y

2y(2x-2x-15)

2y(-15)

-30y

Answer 2

I'm assuming that the x2 is x to the 2nd power...

First factor out what each have in common... a 2y by dividing by 2y...

2y(x^2 - 2x - 15) then find factors of 15 ... 3 * 5 and combine them so that when mulipiled back out you get the middle number...

2y(x - 5)(x + 3)

Answer 3

Is that second two supposed to be an exponent?  I mean, is it actually:

2x²y - 4xy - 30y

If that is the case, then first you would factor out a 2y:

2y (x² - 2x - 15)

Then you would factor the part in parentheses, to get the result:

2y (x - 5) (x + 3)

Answer 4

first you factor out a 2.

2(xy - 2xy - 15y)

next factor out y

2y(x - 2x - 15).  this is the final answer

Answer 5

You have multiples of 2y in each expression so factor it out:

(2x2y divided by 2y equals 2x; 4xy divided by 2y equals 2x and 30y divided by 2y equals 15)

2y ( 2x - 2x - 15) ----> Now, 2x - 2x = 0:

2y ( 0 - 15)

2y ( - 15 )  ----> 2 times -15 is -30; times y = -30y:

-30y
