18x^2-109x+162=0
a = 18; b = -109; c = +162;
Δ = b2-4ac
Δ = -1092-4·18·162
Δ = 217
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{-(-109)-\sqrt{217}}{2*18}=\frac{109-\sqrt{217}}{36} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-109)+\sqrt{217}}{2*18}=\frac{109+\sqrt{217}}{36} $
