X^2+17X-2100=0
a = 1; b = 17; c = -2100;
Δ = b2-4ac
Δ = 172-4·1·(-2100)
Δ = 8689
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{-(17)-\sqrt{8689}}{2*1}=\frac{-17-\sqrt{8689}}{2} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(17)+\sqrt{8689}}{2*1}=\frac{-17+\sqrt{8689}}{2} $
