0,006d2=8

Solution for 0,006d2=8 equation:

0.006d^2=8

We move all terms to the left:

0.006d^2-(8)=0

a = 0.006; b = 0; c = -8;
Δ = b2-4ac
Δ = 02-4·0.006·(-8)
Δ = 0.192
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{0.192}}{2*0.006}=\frac{0-\sqrt{0.192}}{0.012}
=-\frac{\sqrt{}}{0.012}
$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{0.192}}{2*0.006}=\frac{0+\sqrt{0.192}}{0.012}
=\frac{\sqrt{}}{0.012}
