60=30x^2

Solution for 60=30x^2 equation:

60=30x^2

We move all terms to the left:

60-(30x^2)=0

a = -30; b = 0; c = +60;
Δ = b2-4ac
Δ = 02-4·(-30)·60
Δ = 7200
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:

$\sqrt{\Delta}=\sqrt{7200}=\sqrt{3600*2}=\sqrt{3600}*\sqrt{2}=60\sqrt{2}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-60\sqrt{2}}{2*-30}=\frac{0-60\sqrt{2}}{-60}
=-\frac{60\sqrt{2}}{-60}
=-\frac{\sqrt{2}}{-1}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+60\sqrt{2}}{2*-30}=\frac{0+60\sqrt{2}}{-60}
=\frac{60\sqrt{2}}{-60}
=\frac{\sqrt{2}}{-1}
