p^2+5p-649=0
a = 1; b = 5; c = -649;
Δ = b2-4ac
Δ = 52-4·1·(-649)
Δ = 2621
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{-(5)-\sqrt{2621}}{2*1}=\frac{-5-\sqrt{2621}}{2} $$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+\sqrt{2621}}{2*1}=\frac{-5+\sqrt{2621}}{2} $
