4x^2-5x-155=0
a = 4; b = -5; c = -155;
Δ = b2-4ac
Δ = -52-4·4·(-155)
Δ = 2505
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{-(-5)-\sqrt{2505}}{2*4}=\frac{5-\sqrt{2505}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+\sqrt{2505}}{2*4}=\frac{5+\sqrt{2505}}{8} $
