x = 3/2, 4/3

Step-by-step explanation:

16 {x}^{2}  - 3 = (2x + 5)(5x - 3) \\  \\ 16 {x}^{2}  -  3 = 10 {x}^{2}  - 6x + 25x - 15 \\  \\ 16 {x}^{2}  - 10 {x}^{2}  - 3 + 15 = 19x \\  \\ 6 {x}^{2}  - 19x  +  12 = 0 \\  \\ 6{x}^{2}  - 8 {x}^{} - 9 {x}^{}    + 12 = 0 \\  \\ 2x(3x - 4) - 3(3x - 4) = 0 \\  \\ (2x - 3)(3x - 4) = 0

Either, 2x - 3 = 0

2x = 3

x = 3/2

Or, 3x = 4

x = 4/3

Therefore our required answer is x = 3/2, 4/3
