Demonstrates the use of the Quadratic Formula and compares the Formula to solving-by-factoring. ... Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at...
