A model rocket is launched into the air from ground level.
The height, in feet, is modeled by p(x) = -16x2 + 32x, where x is
the number of elapsed seconds. What is the total number of seconds
the model rocket will be in the air?

[tex]p(x)=-16x^2+32x

p(x)=0 [/tex]

[tex]-16x^2+32x = 0[/tex]

[tex]-16x(x-2)=0[/tex]

[tex]x_1=0, x_2=2[/tex]

Rocket will be in the air for 2 seconds.
