2x^2=369

Solution for 2x^2=369 equation:

2x^2=369

We move all terms to the left:

2x^2-(369)=0

a = 2; b = 0; c = -369;
Δ = b2-4ac
Δ = 02-4·2·(-369)
Δ = 2952
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:

$\sqrt{\Delta}=\sqrt{2952}=\sqrt{36*82}=\sqrt{36}*\sqrt{82}=6\sqrt{82}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-6\sqrt{82}}{2*2}=\frac{0-6\sqrt{82}}{4}
=-\frac{6\sqrt{82}}{4}
=-\frac{3\sqrt{82}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+6\sqrt{82}}{2*2}=\frac{0+6\sqrt{82}}{4}
=\frac{6\sqrt{82}}{4}
=\frac{3\sqrt{82}}{2}
