-3x^2+5x+14=0
a = -3; b = 5; c = +14;
Δ = b2-4ac
Δ = 52-4·(-3)·14
Δ = 193
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{193}}{2*-3}=\frac{-5-\sqrt{193}}{-6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+\sqrt{193}}{2*-3}=\frac{-5+\sqrt{193}}{-6} $
