a = -15; b = 55; c = -2;
Δ = b2-4ac
Δ = 552-4·(-15)·(-2)
Δ = 2905
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(55)-\sqrt{2905}}{2*-15}=\frac{-55-\sqrt{2905}}{-30}
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(55)+\sqrt{2905}}{2*-15}=\frac{-55+\sqrt{2905}}{-30}
