Step-by-step explanation:

(x - 4)(2x + 3) = 2 \times 2 \\ x(2x + 3)  - 4(2x + 3)  = 4 \\2 {x}^{2}  + 3x - 8x - 12  - 4 = 0 \\ 2 {x}^{2}  - 5x - 16 = 0

Answer:

(x – 4) (2x + 3) = 2x2

⇒ x (2x + 3) – 4 (2x + 3) = 2x2

⇒ 2x2 + 3x – 8x – 12 = 2x2

⇒ 2x2 + 3x – 8x – 2x2 = 12

⇒ -5x = 12 ⇒ x = 12/-5 = -12/5

∴ x = -2. 2/5
