Question

What are the factors of 5x2 − x − 6?

Answer 1

What are the factors of 5*6=30 that will give you -1?

Answer 2

Is (5x − 1)(x + 6) the answer?

Answer 3

Do you understand how you got that answer?

Answer 4

I saw you put -1 and that was the only answer choice with an -1. Lol

Answer 5

Oh... hmm, well to figure this out if you have to show working is you multiply the coefficient of the x^2 which is 5 by the constant which is -6 to give you -30 and factors of -30 are 1, 2, 3, 5, 6, 10, 15 and 30

Answer 6

@purplec16 It's quite strange to ask ''What are the factors of 5*6=30 that will give you -1''
Since it's NOT 5*6 in this case

You may factor it in this way,
5x^2 − x − 6
= 5x^2 +5x - 6x -6
= 5x (x+1) -6(x+1)
= (5x-6)(x+1)

Answer 7

So then you say well what two factors can give me -1 and from the factors it looks like it is -6x and 5x:

=5x^2-6x+5x+6
=5x^2+5x-6x+6
=5(x+1)-6(x+1)
=(5x-6)(x+1)

Answer 8

Hey guys, please look at the question carefully...
It is 5x^2 − x − 6!!!
The constant term is -6, not -30 or 30!

Answer 9

I got it guys, thanks so much (:

Answer 10

You're welcome... and I do apologize if I may have confused you so please take it to consideration the corrections that they made in using the correct terms so you don't confuse yourself, lol... like I may have confused you.

Answer 11

Lol, math in general confuses me.
