Δ = b2-4ac
Δ = -3522-4·16·0
Δ = 123904
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{123904}=352$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-352)-352}{2*16}=\frac{0}{32}
=0
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-352)+352}{2*16}=\frac{704}{32}
=22
