Question

please solve this question.

Answer 1

12x square-6-9-8x=0
12x square-8x-15=0
12x square+10x-18x-15=0
2x(6x+5)-3(6x+5)=0
(2x-3)(6x+5)=0
so,x=3/2 and x=-5/6

Answer 2

$hii.. \\ \\ = > 12 {x}^{2} - 8x - 6 - 9 = 0 \\ = > 12 {x}^{2} - 8x - 15 = 0 \\ = > 12 {x}^{2} - 18x + 10x - 15 = 0 \\ = > 6x(2x - 3) + 5(2x - 3) = 0 \\ = > (2x - 3)(6x + 5) = 0 \\ = > (2x - 3) = 0 \: and \:(6x + 5) = 0 \\ = > x = \frac{ 3}{2} and \: \frac{ - 5}{6} \\ \\ hope \: this \: helps$
