60.75=3x^2

Solution for 60.75=3x^2 equation:

60.75=3x^2

We move all terms to the left:

60.75-(3x^2)=0

a = -3; b = 0; c = +60.75;
Δ = b2-4ac
Δ = 02-4·(-3)·60.75
Δ = 729
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{729}=27$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-27}{2*-3}=\frac{-27}{-6}
=4+1/2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+27}{2*-3}=\frac{27}{-6}
=-4+1/2
