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

$\sqrt{\Delta}=\sqrt{19600}=140$
$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-140}{2*196}=\frac{-140}{392}
=-5/14
$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+140}{2*196}=\frac{140}{392}
=5/14
