a = 16; b = -410; c = 0;
Δ = b2-4ac
Δ = -4102-4·16·0
Δ = 168100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{168100}=410$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-410)-410}{2*16}=\frac{0}{32}
=0
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-410)+410}{2*16}=\frac{820}{32}
=25+5/8
