H(t)=-16t^2+32t+60

Solution for H(t)=-16t^2+32t+60 equation:

(H)=-16H^2+32H+60

We move all terms to the left:

(H)-(-16H^2+32H+60)=0

We get rid of parentheses

16H^2-32H+H-60=0

We add all the numbers together, and all the variables

16H^2-31H-60=0

a = 16; b = -31; c = -60;
Δ = b2-4ac
Δ = -312-4·16·(-60)
Δ = 4801
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$H_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$H_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$H_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-31)-\sqrt{4801}}{2*16}=\frac{31-\sqrt{4801}}{32}
$
$H_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-31)+\sqrt{4801}}{2*16}=\frac{31+\sqrt{4801}}{32}
