H=16t2+50t

Solution for H=16t2+50t equation:

=16H^2+50H

We move all terms to the left:

-(16H^2+50H)=0

We get rid of parentheses

-16H^2-50H=0

a = -16; b = -50; c = 0;
Δ = b2-4ac
Δ = -502-4·(-16)·0
Δ = 2500
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$H_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$H_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2500}=50$
$H_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-50)-50}{2*-16}=\frac{0}{-32}
=0
$
$H_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-50)+50}{2*-16}=\frac{100}{-32}
=-3+1/8
