The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-98)-\sqrt{7989}}{2*85}=\frac{98-\sqrt{7989}}{170}
$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-98)+\sqrt{7989}}{2*85}=\frac{98+\sqrt{7989}}{170}
