Answer 2

Answer:

$3 {x}^{2} + 2x - 1 \\ by \: middle \: term \: spitting \\ we \: get \\ = 3 {x}^{2} + 3x - x - 1 \\ = 3x(x + 1) - 1(x + 1) \\ = (x + 1)(3x - 1) \\ if \\ x + 1 = 0 \\ x = 1 \\ \\ if \\ 3x - 1 = 0 \\ x = \frac{1}{3} \\ therefore \: value</em></strong><strong><em>\: of \: x \: are \: 1 \: and \: \frac{1}{3}$

hope it helps...✌️
