8+3x-2x^2=0
a = -2; b = 3; c = +8;
Δ = b2-4ac
Δ = 32-4·(-2)·8
Δ = 73
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{-(3)-\sqrt{73}}{2*-2}=\frac{-3-\sqrt{73}}{-4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{73}}{2*-2}=\frac{-3+\sqrt{73}}{-4} $
