15x^2-11x-8=0
a = 15; b = -11; c = -8;
Δ = b2-4ac
Δ = -112-4·15·(-8)
Δ = 601
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{-(-11)-\sqrt{601}}{2*15}=\frac{11-\sqrt{601}}{30} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+\sqrt{601}}{2*15}=\frac{11+\sqrt{601}}{30} $
