Multiplying two Binomials You've used the FOIL method for multiplying binomial expressions, but if you're like most of us, you just plugged and chugged to get the work done. Here's a tool that allows you to play with the values and see how changing individual parameters changes the graph of the equation. Tick the box for perfect squares and see what varying a parameter on a square does to the plot! Multiply two Binomials; Plot the Quadratic
Multiplying three Binomials That tool is for multiplying two binomial expressions, but what about three? Here's a tool that allows you to change the parameters in isolation on any part of three binomials and immediately see the change. This tool shows you a plot of the cubic instantly, and includes a checkbox to constrain the equations to perfect cubes. Multiply three Binomials; Plot the Cubic
