20x^2-157x-78=0
a = 20; b = -157; c = -78;
Δ = b2-4ac
Δ = -1572-4·20·(-78)
Δ = 30889
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{-(-157)-\sqrt{30889}}{2*20}=\frac{157-\sqrt{30889}}{40} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-157)+\sqrt{30889}}{2*20}=\frac{157+\sqrt{30889}}{40} $
