12x^2-2x=33

Solution for 12x^2-2x=33 equation:

12x^2-2x=33

We move all terms to the left:

12x^2-2x-(33)=0

a = 12; b = -2; c = -33;
Δ = b2-4ac
Δ = -22-4·12·(-33)
Δ = 1588
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:

$\sqrt{\Delta}=\sqrt{1588}=\sqrt{4*397}=\sqrt{4}*\sqrt{397}=2\sqrt{397}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-2)-2\sqrt{397}}{2*12}=\frac{2-2\sqrt{397}}{24}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2)+2\sqrt{397}}{2*12}=\frac{2+2\sqrt{397}}{24}
