Question

Which of the following shows the factors of 2y2 - 2y - 4?

Answer 1

Well we can make the problem easier by factoring out the 2, so you have \[2y^2-2y-4 =~ 2(y^2-y-2)\]

Now can you find two numbers whose product is -2 and sum is -1?

Answer 2

ok umm im not really good at this :x which sucks but um i have these choices
(2y - 4)(y - 1)

(2y - 4)(y + 1)

(2y - 2)(y - 2)

(2y - 2)(y + 2)

Answer 3

Well I don't care for the choices, the whole point is for you to understand the process.
