12x^2=132

Solution for 12x^2=132 equation:

12x^2=132

We move all terms to the left:

12x^2-(132)=0

a = 12; b = 0; c = -132;
Δ = b2-4ac
Δ = 02-4·12·(-132)
Δ = 6336
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:

$\sqrt{\Delta}=\sqrt{6336}=\sqrt{576*11}=\sqrt{576}*\sqrt{11}=24\sqrt{11}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24\sqrt{11}}{2*12}=\frac{0-24\sqrt{11}}{24}
=-\frac{24\sqrt{11}}{24}
=-\sqrt{11}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24\sqrt{11}}{2*12}=\frac{0+24\sqrt{11}}{24}
=\frac{24\sqrt{11}}{24}
=\sqrt{11}
