98x^2-15x-2=0
a = 98; b = -15; c = -2;
Δ = b2-4ac
Δ = -152-4·98·(-2)
Δ = 1009
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{-(-15)-\sqrt{1009}}{2*98}=\frac{15-\sqrt{1009}}{196} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-15)+\sqrt{1009}}{2*98}=\frac{15+\sqrt{1009}}{196} $
