Quadratic function word problems practice general idea regarding projectile motion: 1 the force of gravity pulling it back down (always -16 ft/sec -98m/sec coefficient of the squared term) 2 the initial velocity (v0 ) at which it was thrown/dropped (always goes with the middle term) 3 the initial height (s0 ) from which it was thrown/dropped.

Quadratic equations - word problems with solutions in this tutorial, you will learn: solving word problems with quadratic equations how to build up a quadratic equation from a real life example how to solve the quadratic equation to find the required outcome. A negative root, though a valid solution to a quadratic equation, may not be the answer that a word problem is looking for a positive root, or possibly roots, then is the more appropriate final answer. Quadratic applications are very helpful in solving several types of word problems (other than the bouquet throwing problem), especially where optimization is involved again, we can use the vertex to find the maximum or the minimum values, and roots to find solutions to quadratics.
