Answer:

$3 {q}^{2} = 2q + 8 \\ \\ = > 3 {q}^{2} - 2q - 8 = 0 \\ \\ = > 3 {q}^{2} - (6 - 4)q - 8 = 0 \\ \\ = > 3 {q}^{2} - 6q + 4q - 8 = 0 \\ \\ = > 3q(q - 2) + 4(q - 2) = 0 \\ \\ = > (3q + 4)(q - 2) = 0 \\ \\ either \: 3q + 4 = 0 \\ \\ = > 3q = - 4 \\ \\ = > q = \frac{ - 4}{3} \\ \\ or \: q - 2 = 0 \\ \\ = > q = 2$
