Ideas in this lesson
Polynomial long division
Divide leading terms, multiply the divisor, subtract, and bring down the next term.
Synthetic division
For a divisor x − r, use r and include a zero coefficient for every missing power.
Quotient and remainder
Write P(x) = D(x)Q(x) + R(x), with the remainder degree less than the divisor degree.
