a = -1; b = 1; c = -0.000525;
Δ = b2-4ac
Δ = 12-4·(-1)·(-0.000525)
Δ = 0.9979
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)-\sqrt{0.9979}}{2*-1}=\frac{-1-\sqrt{0.9979}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{0.9979}}{2*-1}=\frac{-1+\sqrt{0.9979}}{-2}
