x^2-120x+216=0
a = 1; b = -120; c = +216;
Δ = b2-4ac
Δ = -1202-4·1·216
Δ = 13536
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{13536}=\sqrt{144*94}=\sqrt{144}*\sqrt{94}=12\sqrt{94}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-120)-12\sqrt{94}}{2*1}=\frac{120-12\sqrt{94}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-120)+12\sqrt{94}}{2*1}=\frac{120+12\sqrt{94}}{2} $
