0.5x^2=615

Solution for 0.5x^2=615 equation:

0.5x^2=615

We move all terms to the left:

0.5x^2-(615)=0

a = 0.5; b = 0; c = -615;
Δ = b2-4ac
Δ = 02-4·0.5·(-615)
Δ = 1230
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{1230}}{2*0.5}=\frac{0-\sqrt{1230}}{1}
=-\frac{\sqrt{}}{1}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{1230}}{2*0.5}=\frac{0+\sqrt{1230}}{1}
=\frac{\sqrt{}}{1}
