0=-16t^2+14

Solution for 0=-16t^2+14 equation:

0=-16t^2+14

We move all terms to the left:

0-(-16t^2+14)=0

We add all the numbers together, and all the variables

-(-16t^2+14)=0

We get rid of parentheses

16t^2-14=0

a = 16; b = 0; c = -14;
Δ = b2-4ac
Δ = 02-4·16·(-14)
Δ = 896
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{896}=\sqrt{64*14}=\sqrt{64}*\sqrt{14}=8\sqrt{14}$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-8\sqrt{14}}{2*16}=\frac{0-8\sqrt{14}}{32}
=-\frac{8\sqrt{14}}{32}
=-\frac{\sqrt{14}}{4}
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+8\sqrt{14}}{2*16}=\frac{0+8\sqrt{14}}{32}
=\frac{8\sqrt{14}}{32}
=\frac{\sqrt{14}}{4}
