Answer 2

Step-by-step explanation:

$3 {x}^{2} + 11x - 4 \\ \\ 3 {x}^{2} + 12x - x - 4 \: \\ ( by \: middle \: term \: split)\\ \\ 3x(x + 4) - 1(x + 4) \\ \\ (3x - 1)(x + 4) \\ \\ then \\ \\ 3x - 1 = 0 \: \: \: \:and \: \: x + 4 = 0 \\ \\ 3x = 1 \: \: and \: \: \: x = - 4 \\ \\ x = \frac{1}{3} and \: \: \: x = - 4$
