-16t^2+272t=0

Solution for -16t^2+272t=0 equation:

-16t^2+272t=0

a = -16; b = 272; c = 0;
Δ = b2-4ac
Δ = 2722-4·(-16)·0
Δ = 73984
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{73984}=272$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(272)-272}{2*-16}=\frac{-544}{-32}
=+17
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(272)+272}{2*-16}=\frac{0}{-32}
=0
