k^2-9k-24=0
a = 1; b = -9; c = -24;
Δ = b2-4ac
Δ = -92-4·1·(-24)
Δ = 177
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-9)-\sqrt{177}}{2*1}=\frac{9-\sqrt{177}}{2} $$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-9)+\sqrt{177}}{2*1}=\frac{9+\sqrt{177}}{2} $
