5r^2-24r-5=0
a = 5; b = -24; c = -5;
Δ = b2-4ac
Δ = -242-4·5·(-5)
Δ = 676
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{676}=26$$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-26}{2*5}=\frac{-2}{10} =-1/5 $$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+26}{2*5}=\frac{50}{10} =5 $
