6x^2-12x-220=0
a = 6; b = -12; c = -220;
Δ = b2-4ac
Δ = -122-4·6·(-220)
Δ = 5424
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{5424}=\sqrt{16*339}=\sqrt{16}*\sqrt{339}=4\sqrt{339}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-12)-4\sqrt{339}}{2*6}=\frac{12-4\sqrt{339}}{12} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-12)+4\sqrt{339}}{2*6}=\frac{12+4\sqrt{339}}{12} $
