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

$\sqrt{\Delta}=\sqrt{4900}=70$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-70}{2*7}=\frac{-70}{14}
=-5
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+70}{2*7}=\frac{70}{14}
=5
