3. Polynomial Forms As you know, polynomials are in the form… And they have a finite number of terms (not infinite). Smaller polynomials have special names. MonomialBinomial Trinomial The focus of this lesson is multiplying binomials. Last lesson we saw a pattern named Pascal’s Triangle.

4. Binomial Expansion The triangle can continue downwards further. Hopefully you understand the number pattern!

5. Binomial Expansion The triangle refers to the coefficients of each term.
