Answer 2

$\\ 6x {}^{2} - 3x - 9 = 0 \\ \\ \frac{6x {}^{2} }{3} - \frac{3x}{3} - \frac{9}{3} = \frac{0}{3} \\ \\ 2x {}^{2} - x - 3 = 0 \\ \\2x {}^{2} - 2x - 3x - 3 = 0 \\ \\ 2x(x + 1) - 3(x + 1) = 0$

$\\ (x + 1)(2x - 3) = 0 \\ \\ x + 1 = 0 \\ x = - 1 \\ \\ \\ 2x - 3 = 0 \\ 2x = 3 \\ x = \frac{3}{2}$

x1 = - 1

x1 = - 1x2 = 3/2
