a = 007; b = -1.7; c = 0;
Δ = b2-4ac
Δ = -1.72-4·007·0
Δ = 2.89
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{-(-1.7)-\sqrt{2.89}}{2*007}=\frac{1.7-\sqrt{2.89}}{14}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1.7)+\sqrt{2.89}}{2*007}=\frac{1.7+\sqrt{2.89}}{14}
