Texas Instruments: The Binomial Formula: Its Expansion Using Pascal's

There are particular ways to multiply binomials. One could use the FOIL method or employ the distributive property. Sal walks through each step of the FOIL method and then shows that using distribution results in the same answer. This is...

This video is the first installment in a series devoted to exploring Heron's Formula. It is a high-level experience that delves into proof using algebra. It demonstrates a step-by-step process for finding the area of a triangle using...

Where many multiplying binomial lessons introduce the tool of FOIL and move on, this video presentation really delves into the how's and why's of the distributive property. Careful treatment of distribution and explicitly written out...

Students will try to determine a pattern for expanding binomials by using the expand command. Students will then make a conjecture about the expansion of a more complex pair of binomials. Students will then use SMG to take a closer look...

In this Derive activity, students use the Remainder Theorem to find a tangent line to the graph of a polynomial function.

The purpose of the activity is for students to verify the results of the Midpoint Formula using the dynamic capabilities of Cabri Jr.

There has got to be a better way; you just have to find it! Given a general binomial to expand with increasing powers, pupils realize that there must be a better way than multiple multiplications. Classmates look for patterns and use...

This worksheet is part of the TI-Nspire activity on the quadratic formula. Pupils determine the solutions of a quadratic function by looking at a graph and the discriminant. They use the quadratic formula to solve quadratic functions on...

Students expand expressions using Pascal's Triangle and verify the results on a Computer Algebra System CAS tool.

What is the difference of a cube? When is it used? How does it work? Use it to factor a binomial involving subtraction. Rewrite the terms as a cubed expression. Then apply the difference of cubes formula. Don't forget to simplify. Still...
