-3x^2-7x+18=0
a = -3; b = -7; c = +18;
Δ = b2-4ac
Δ = -72-4·(-3)·18
Δ = 265
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{-(-7)-\sqrt{265}}{2*-3}=\frac{7-\sqrt{265}}{-6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+\sqrt{265}}{2*-3}=\frac{7+\sqrt{265}}{-6} $
