Solution :

 \:  \:  \:  \:  \: (2x + 3)(x - 4) = 6

 =  >   {2x}^{2}  - 8x + 3x - 12 = 6

 =  >  {2x}^{2}  - 5x - 12 = 6

 =  >  {2x}^{2}  - 5x - 12 - 6 = 0

 =  >  {2x}^{2}  - 5x - 18 = 0

 =  >  {2x}^{2}  - 9x + 4x - 18 = 0

 =  > x(2x - 9) + 2(2x - 9) = 0

 =  > (2x - 9)(x + 2) = 0

 =  > 2x - 9 = 0 \:  \:  \:  \: or \:  \:  \:  \:  x + 2 = 0

 =  > 2x = 9 \:  \:  \:  \: or \:  \:  \:  \: x =  - 2

 =  > x =  \frac{9}{2}  \:  \:  \:  \: or \:  \:  \:  \: x =  - 2.
