5/11x+2/3x-189-1/6=0

We calculate fractions


(-99x^2)/1188x^2+540x/1188x^2+792x/1188x^2-189=0

We multiply all the terms by the denominator


(-99x^2)+540x+792x-189*1188x^2=0

We add all the numbers together, and all the variables

(-99x^2)+1332x-189*1188x^2=0

Wy multiply elements

(-99x^2)-224532x^2+1332x=0

We get rid of parentheses

-99x^2-224532x^2+1332x=0

We add all the numbers together, and all the variables

-224631x^2+1332x=0

a = -224631; b = 1332; c = 0;
Δ = b2-4ac
Δ = 13322-4·(-224631)·0
Δ = 1774224
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1774224}=1332$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1332)-1332}{2*-224631}=\frac{-2664}{-449262}
=148/24959
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1332)+1332}{2*-224631}=\frac{0}{-449262}
=0
