Answer:

heya mate ☺

 \frac{x ^{2} + 1 }{3x}  +  \frac{5}{6}  = 0 \\ \\   =  > \frac{6(x ^{2}  + 1) + 5 \times 3x}{3x \times 6}  = 0 \\  =  > 6x ^{2}  + 6 + 15x = 3x \times 6 \times 0 \\  =  > 6x ^{2}  + 15x + 6 = 0 \\  =  > 3(2x ^{2}  + 5x + 2) = 0 \\   = > 2x ^{2}  + 5x + 2 = 0 \\  =  > 2x ^{2}  + (4 + 1)x + 2 = 0  \\   = > 2x ^{2}  + 4x + x + 2 = 0 \\   = > 2x(x + 2) + 1(x + 2) = 0 \\  =  > (2x + 1)(x + 2) = 0 \\ either \: 2x + 1 = 0 \\  =  > 2x =  - 1 =  > x =  \frac{ - 1}{2}  \\ or \:  x+ 2 = 0 \\  =  > x =  - 2

hope it helps u
