0.03x^2=31

Solution for 0.03x^2=31 equation:

0.03x^2=31

We move all terms to the left:

0.03x^2-(31)=0

a = 0.03; b = 0; c = -31;
Δ = b2-4ac
Δ = 02-4·0.03·(-31)
Δ = 3.72
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{3.72}}{2*0.03}=\frac{0-\sqrt{3.72}}{0.06}
=-\frac{\sqrt{}}{0.06}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{3.72}}{2*0.03}=\frac{0+\sqrt{3.72}}{0.06}
=\frac{\sqrt{}}{0.06}
