Question

$\frac{{x}^{2} - (x + 1)(x + 2)}{5x + 1} = 6$

Answer 1

x²-(x²+2x+x+2)/(5x+1)=6
x²-x²-3x-2/(5x+1)=6
-(3x+2)/(5x+1)=6
-3x-2=30x+6
30x+3x=-8
x=-8/33

Answer 2

➡HERE IS YOUR ANSWER⬇

$\frac{ {x}^{2} - (x + 1)(x + 2)}{5x + 1} = 6 \\ \\ or \: \: {x}^{2} - ( {x}^{2} + 3x + 2) = 6(5x + 1) \\ \\ or \: \: - 3x - 2 = 30x + 6 \\ \\ or \: \: 33x = - 8 \\ \\ or \: \: x = - \frac{8}{33}$
