3x^2=79

Solution for 3x^2=79 equation:

3x^2=79

We move all terms to the left:

3x^2-(79)=0

a = 3; b = 0; c = -79;
Δ = b2-4ac
Δ = 02-4·3·(-79)
Δ = 948
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:

$\sqrt{\Delta}=\sqrt{948}=\sqrt{4*237}=\sqrt{4}*\sqrt{237}=2\sqrt{237}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{237}}{2*3}=\frac{0-2\sqrt{237}}{6}
=-\frac{2\sqrt{237}}{6}
=-\frac{\sqrt{237}}{3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{237}}{2*3}=\frac{0+2\sqrt{237}}{6}
=\frac{2\sqrt{237}}{6}
=\frac{\sqrt{237}}{3}
