Solution for 12x2/3=83 equation:



12x^2/3=83
We move all terms to the left:
12x^2/3-(83)=0
We multiply all the terms by the denominator
12x^2-83*3=0
We add all the numbers together, and all the variables
12x^2-249=0
a = 12; b = 0; c = -249;
Δ = b2-4ac
Δ = 02-4·12·(-249)
Δ = 11952
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{11952}=\sqrt{144*83}=\sqrt{144}*\sqrt{83}=12\sqrt{83}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{83}}{2*12}=\frac{0-12\sqrt{83}}{24} =-\frac{12\sqrt{83}}{24} =-\frac{\sqrt{83}}{2} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{83}}{2*12}=\frac{0+12\sqrt{83}}{24} =\frac{12\sqrt{83}}{24} =\frac{\sqrt{83}}{2} $
