3x^2=3888

Solution for 3x^2=3888 equation:

3x^2=3888

We move all terms to the left:

3x^2-(3888)=0

a = 3; b = 0; c = -3888;
Δ = b2-4ac
Δ = 02-4·3·(-3888)
Δ = 46656
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{46656}=216$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-216}{2*3}=\frac{-216}{6}
=-36
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+216}{2*3}=\frac{216}{6}
=36
