22x^2+9x-31=0
a = 22; b = 9; c = -31;
Δ = b2-4ac
Δ = 92-4·22·(-31)
Δ = 2809
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{2809}=53$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-53}{2*22}=\frac{-62}{44} =-1+9/22 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+53}{2*22}=\frac{44}{44} =1 $
