t=-16t^2+48t+100

Solution for t=-16t^2+48t+100 equation:

t=-16t^2+48t+100

We move all terms to the left:

t-(-16t^2+48t+100)=0

We get rid of parentheses

16t^2-48t+t-100=0

We add all the numbers together, and all the variables

16t^2-47t-100=0

a = 16; b = -47; c = -100;
Δ = b2-4ac
Δ = -472-4·16·(-100)
Δ = 8609
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-47)-\sqrt{8609}}{2*16}=\frac{47-\sqrt{8609}}{32}
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-47)+\sqrt{8609}}{2*16}=\frac{47+\sqrt{8609}}{32}
