If an object is projected upward with an initial velocity of \(64 \mathrm{ft}\) per sec from a height of \(80 \mathrm{ft}\), then its height in feet \(t\) seconds after it is projected is modeled by the function $$ f(t)=-16 t^{2}+64 t+80. $$ How long after it is projected will it hit the ground? (Hint: When it hits the ground, its height is \(0 \mathrm{ft} .)\)
The binomial \(x^{6}-y^{6}\) may be considered as either a difference of squares or a difference of cubes. Factor \(x^{6}-y^{6}\) by first factoring as a difference of squares. Then factor further by considering one of the factors as a sum of cubes and the other factor as a difference of cubes.
The following exercises are of mixed variety. Factor each polynomial. $$ 16 x^{3}+32 x^{2}-9 x-18 $$
Solve each equation. $$ 6 x^{3}-13 x^{2}-5 x=0 $$
Factor each trinomial. \(4(m-5)^{2}-4(m-5)-15\)
