Question

the factor of 12x square minus x minus 6

Answer 1

Answer:

${12x}^{2} - x - 6 \\ = {12x}^{2} - (9 - 8)x - 6 \\ = {12x}^{2} - 9x - 8x - 6 \\ = 3x(4x - 3) + 2(4x - 6) \\ = (4x - 3)(3x + 2) \\ = 4x - 3 = 0 \: or \: 3x + 2 = 0 \\ x = \frac{3}{4} \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{ - 2}{3}$
