Projectile is launched into the air. the function h(t) = -16t4 + 32t + 128 gives
the height, h, in feet, of the projectile t seconds after it is launched. after how
many seconds will the projectile land back on the ground?

it is for factor form of a quadratic function

Find the value of 1715⋅211.though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult. give the numerator followed by the denominator, separated by a comma.
