a = 1; b = 9; c = -699;
Δ = b2-4ac
Δ = 92-4·1·(-699)
Δ = 2877
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{-(9)-\sqrt{2877}}{2*1}=\frac{-9-\sqrt{2877}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{2877}}{2*1}=\frac{-9+\sqrt{2877}}{2}
