3x*x=4800

Solution for 3x*x=4800 equation:

3x*x=4800

We move all terms to the left:

3x*x-(4800)=0

Wy multiply elements

3x^2-4800=0

a = 3; b = 0; c = -4800;
Δ = b2-4ac
Δ = 02-4·3·(-4800)
Δ = 57600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{57600}=240$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-240}{2*3}=\frac{-240}{6}
=-40
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+240}{2*3}=\frac{240}{6}
=40
