The document discusses using the quadratic formula to solve quadratic equations. It provides the standard form of a quadratic equation, ax2 + bx + c = 0, and explains that the quadratic formula, x = (-b ± √(b2 - 4ac))/2a, can be used to find the solutions. Several examples of using the quadratic formula to solve quadratic equations are shown. The document also discusses using a vertical motion formula, h = -16t2 + vt + s, to calculate the time for a model rocket to reach a given altitude based on its initial velocity and starting height.
