3x^2-18=5x
We move all terms to the left:
3x^2-18-(5x)=0
a = 3; b = -5; c = -18;
Δ = b2-4ac
Δ = -52-4·3·(-18)
Δ = 241
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{-(-5)-\sqrt{241}}{2*3}=\frac{5-\sqrt{241}}{6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+\sqrt{241}}{2*3}=\frac{5+\sqrt{241}}{6} $
