Question

inverse trigonometric functions ​

Answer 1

Answer:

$\huge\mathfrak\orange {Answer}$

$\frac{x - 1}{x + 1} + \frac{2x - 1}{2x + 1} = \frac{23}{36}$

$[ 1 - \frac{(x - 1)(2x - 1)}{(x + 1)(2x + 1)} ]$

$24 {x}^{2} - 23x - 12 = 0 = (3x - 4)(8x + 3)=0\huge\mathfrak\blue { Answer = (D) none of these }$
