Answer 2

Explanation:

(2q-3)(q-4) = 18

$2q {}^{2} - 8q - 3q + 12 = 18$

$2q {}^{2} - 11q + 12 = 18$

$2 {q}^{2} - 11q + 12 - 18=0$

$2q {}^{2} - 11q - 6 = 0$

$2q {}^{2} - 12q + q - 6 = 0$

2q( q - 6) + 1 ( q - 6 ) = 0

(2q + 1) ( q - 6) =0

2q + 1 = 0. and. q - 6 = 0

q = -1 /2. q = 6

therefore, the answer is (-1/2) and 6.
