Question

A ball is hit vertically into the air using a paddle at a speed of 32 ft/sec. The expression -16t^2 + 32t give the ball's height after t seconds. Factor this expression.

Answer 1

-16t(t - 2).

Explanation:

-16t^2 + 32t The GCF is -16t so we have:

-16t(t - 2).

Answer 2

-16t (t-2)

Explanation:

−16t² + 32t = 256t² + 32t

Factor out the GCF:

-16t (t-2)
