Solve Using the Quadratic Formula h=-16t^2+80

$h = - 16 t^{2} + 80$

Move all the expressions to the left side of the equation.

Add $16 t^{2}$ to both sides of the equation.

$h + 16 t^{2} = 80$

Subtract $80$ from both sides of the equation.

$h + 16 t^{2} - 80 = 0$

Move all terms not containing $h$ to the right side of the equation.

Subtract $16 t^{2}$ from both sides of the equation.

$h - 80 = - 16 t^{2}$

Add $80$ to both sides of the equation.

$h = - 16 t^{2} + 80$
