Multiplying Polynomials

The idea
Polynomials multiply by distribution: each term of one factor multiplies each term of the other, and the products add.
In practice
2x(3x + 4) = 6x² + 8x. With longer factors the bookkeeping grows; the rule never changes.
Where people slip
Multiply coefficients and add exponents within each product.
