## lalaland_lauren one year ago What are the factors of 3x2 + 13x + 4? (3x + 1)(x + 4) (3x + 4)(x + 1) (3x − 4)(x + 1) (3x − 1)(x + 4)

1. Mertsj

Why don't you use FOIL and multiply each answer choice to see which one gives 3x^2+13x+4???

2. lalaland_lauren

FOIL confuses me with these kinds of equations though

3. Mertsj

All the more reason to practice it.

$\mathrm{Factor}\:3x^2+13x+4:\quad \left(x+4\right)\left(3x+1\right)$
