Question

Factor completely.
3x2 – X – 2

Answer 1

`x = 1 \: \: \: \: or \: \: \: \: x = - (2)/(3) \\`

Explanation:

`{3x}^(2) - x - 2 = 0 \\ {3x}^(2) - 3x + 2x - 2 = 0 \\ 3x(x - 1) + 2(x - 1) = 0 \\ (x - 1)(3x + 2) = 0 \\ x - 1 = 0 \: \: \: \: or \: \: \: \: 3x + 2 = 0 \\ x = 1 \: \: \: \: or \: \: \: \: x = - (2)/(3)`
