2x^2+11x-434=0
a = 2; b = 11; c = -434;
Δ = b2-4ac
Δ = 112-4·2·(-434)
Δ = 3593
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{3593}}{2*2}=\frac{-11-\sqrt{3593}}{4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(11)+\sqrt{3593}}{2*2}=\frac{-11+\sqrt{3593}}{4} $
