2k^2-8k-120=0
a = 2; b = -8; c = -120;
Δ = b2-4ac
Δ = -82-4·2·(-120)
Δ = 1024
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}$$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1024}=32$$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-8)-32}{2*2}=\frac{-24}{4} =-6 $$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-8)+32}{2*2}=\frac{40}{4} =10 $
