3x^2+2+112=180

Solution for 3x^2+2+112=180 equation:

3x^2+2+112=180

We move all terms to the left:

3x^2+2+112-(180)=0

We add all the numbers together, and all the variables

3x^2-66=0

a = 3; b = 0; c = -66;
Δ = b2-4ac
Δ = 02-4·3·(-66)
Δ = 792
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:

$\sqrt{\Delta}=\sqrt{792}=\sqrt{36*22}=\sqrt{36}*\sqrt{22}=6\sqrt{22}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-6\sqrt{22}}{2*3}=\frac{0-6\sqrt{22}}{6}
=-\frac{6\sqrt{22}}{6}
=-\sqrt{22}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+6\sqrt{22}}{2*3}=\frac{0+6\sqrt{22}}{6}
=\frac{6\sqrt{22}}{6}
=\sqrt{22}
