3x^2=265

Solution for 3x^2=265 equation:

3x^2=265

We move all terms to the left:

3x^2-(265)=0

a = 3; b = 0; c = -265;
Δ = b2-4ac
Δ = 02-4·3·(-265)
Δ = 3180
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:

$\sqrt{\Delta}=\sqrt{3180}=\sqrt{4*795}=\sqrt{4}*\sqrt{795}=2\sqrt{795}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{795}}{2*3}=\frac{0-2\sqrt{795}}{6}
=-\frac{2\sqrt{795}}{6}
=-\frac{\sqrt{795}}{3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{795}}{2*3}=\frac{0+2\sqrt{795}}{6}
=\frac{2\sqrt{795}}{6}
=\frac{\sqrt{795}}{3}
