Step-by-step explanation:

according \: \: to \: question \\  \frac{2}{(x + 1)}  +  \frac{3}{2(x - 2)}  =  \frac{23}{5x}  \\  \frac{4(x - 2) + 3(x + 1)}{2(x + 1)(x - 2)}  =  \frac{23}{5x}  \\  \frac{4x - 8 + 3x + 3}{2(x + 1)(x - 2)}  =  \frac{23}{5x}  \\ 20 {x}^{2}  - 40x + 15x + 15 {x}^{2}  = 46(x + 1)(x - 2) \\ on \: solving \: this \: we \: get \: the \: equation \\ 11 {x}^{2}  - 21x - 92 = 0 \\ by \: quadratic \: formula \\ x = 4 \: and \:  \\ x =  \frac{21 - 67}{22}  =  \frac{ - 46}{22}

the roots are. 4 and -46/22
