Question

Confused. :(
Factor 8x^2 + 2x – 3.

A. (2x + 3)(4x – 1)
B. (8x + 1)(x – 3)
C. The polynomial is prime.
D. (2x – 1)(4x + 3)

Answer 1

Do you know how to factor?

Answer 2

Um. I think. >_<

Answer 3

You think. Hmm... this one's a little different because of the \(8x^2\)

Answer 4

so do you know what to do first?

Answer 5

Yes. You must find the factors of 8 and 3.

Answer 6

Answer: D

Answer 7

Um. I am looking more for an explanation. @Jake_Litt ._.

Answer 8

Well, actually, you don't have to... um just multiply each of the answers out and see which one gives you \(8x^2+2x-3\)

Answer 9

If you use the FOIL method with D you will get the answer 8x^2 + 2x – 3.
8x^2 + 2x – 3
(2x – 1)(4x + 3)
=8x^2 + 2x – 3
First find the factors for 2x and -3, then look check for the factors of 8 that will get -2x as an answer
Is my explanation clear?
