-16t^2+230t=0

Solution for -16t^2+230t=0 equation:

-16t^2+230t=0

a = -16; b = 230; c = 0;
Δ = b2-4ac
Δ = 2302-4·(-16)·0
Δ = 52900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{52900}=230$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(230)-230}{2*-16}=\frac{-460}{-32}
=14+3/8
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(230)+230}{2*-16}=\frac{0}{-32}
=0
