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

$\sqrt{\Delta}=\sqrt{3136}=56$
$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-56}{2*49}=\frac{-56}{98}
=-4/7
$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+56}{2*49}=\frac{56}{98}
=4/7
