x2=6120

Solution for x2=6120 equation:

x2=6120

We move all terms to the left:

x2-(6120)=0

We add all the numbers together, and all the variables

x^2-6120=0

a = 1; b = 0; c = -6120;
Δ = b2-4ac
Δ = 02-4·1·(-6120)
Δ = 24480
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:

$\sqrt{\Delta}=\sqrt{24480}=\sqrt{144*170}=\sqrt{144}*\sqrt{170}=12\sqrt{170}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{170}}{2*1}=\frac{0-12\sqrt{170}}{2}
=-\frac{12\sqrt{170}}{2}
=-6\sqrt{170}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{170}}{2*1}=\frac{0+12\sqrt{170}}{2}
=\frac{12\sqrt{170}}{2}
=6\sqrt{170}
