2x^2-13x=6=0
We move all terms to the left:
2x^2-13x-(6)=0
a = 2; b = -13; c = -6;
Δ = b2-4ac
Δ = -132-4·2·(-6)
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{-(-13)-\sqrt{217}}{2*2}=\frac{13-\sqrt{217}}{4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+\sqrt{217}}{2*2}=\frac{13+\sqrt{217}}{4} $
