5.2 Polynomial Division
Day 1 Long Division
To divide a polynomial by a
monomial, divide each term in the
numerator by the term in the
denominator.
Recall long division
Now apply to polynomials
Use long division to find (x2 – 2x – 15) ÷ (x – 5).
to (a2 – 5a + 3)(2 – a)–1
(4y3 − 6y2 + 4y − 1) ÷ (2y − 1)
Use long division to find (4x2 + 8x + 5) ÷ (2x + 3).
Day two Synthetic Division
Use synthetic division to find (x3 – 4x2 + 6x – 4) ÷ (x – 2).
Use synthetic division to find (x2 + 8x + 9) ÷ (x + 1).
(3c4 + 6c3 - 2c + 4)(c + 2)-1
Use synthetic division to find (4y3 – 6y2 + 4y – 1) ÷ (2y – 1).
Divide the numerator and denominator by the leading coefficient
(6 𝑦2– 5 𝑦 – 15)(2 𝑦+3)–1
