Question

What is the factored form of 3x2+5-12?

(3x+3)(x+4)

(3x-1)(x-4)

(3x+4)(x-3)

(3x-4)(x+3

Answer 1

I keep getting \[3x ^{2}-7\]

Answer 2

I'm pretty sure you can factor it out more

Answer 3

is there supposed to be another x in your problem....like 5x ?

Answer 4

Yes. It was a typo. Sorry

Answer 5

(3x - 4)(x + 3)

check by FOIL
3x^2 + 9x - 4x - 12 (combine like terms)
3x^2 + 5x - 12
