3x^2-25x-84=0
a = 3; b = -25; c = -84;
Δ = b2-4ac
Δ = -252-4·3·(-84)
Δ = 1633
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{-(-25)-\sqrt{1633}}{2*3}=\frac{25-\sqrt{1633}}{6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-25)+\sqrt{1633}}{2*3}=\frac{25+\sqrt{1633}}{6} $
