4x^2-11x-22=0
a = 4; b = -11; c = -22;
Δ = b2-4ac
Δ = -112-4·4·(-22)
Δ = 473
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{473}}{2*4}=\frac{11-\sqrt{473}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+\sqrt{473}}{2*4}=\frac{11+\sqrt{473}}{8} $
