2x^2+15x-236=0
a = 2; b = 15; c = -236;
Δ = b2-4ac
Δ = 152-4·2·(-236)
Δ = 2113
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{-(15)-\sqrt{2113}}{2*2}=\frac{-15-\sqrt{2113}}{4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+\sqrt{2113}}{2*2}=\frac{-15+\sqrt{2113}}{4} $
