Polynomial long division is a method for dividing a polynomial by another polynomials of a lower degree.
It is very similar to dividing numbers.
Guided Practice:
6. (2𝑥 3 – 9𝑥 2 + 𝑥 + 3) ÷ (2𝑥 + 1)
Simplify the polynomial by performing the indicated operation.
1. 𝑓𝑔(𝑓 4 + 2𝑓 3 𝑔 – 3𝑓 2 𝑔2 + 𝑓𝑔2 )
2. (𝑦 2 − 7𝑦 + 5)(𝑦 2 – 𝑦 – 3)
3. (−𝑥 2 + 2𝑥 3 + 25) ÷ (𝑥 – 3)
4. (2𝑥 – 5)4

8. (15𝑥 2 + 8𝑥 − 12) ÷ (3𝑥 + 1)
9. (𝑥 + 7)2 – (4𝑥 – 10)
1. Synthetic division is a process that can be used as an alternative to long division. Synthetic division
can be used when the divisor is a _____________ binomial with a leading ________________ of one.
Divide using long and synthetic division. Determine whether the given binomial is a factor of p(x).
1. (2𝑥 + 1) ∶ 𝑝(𝑥) = 10𝑥 3 + 7𝑥 2 − 3𝑥 – 5
2. (𝑥 + 3) ∶ 𝑝(𝑥) = 𝑥 3 − 4𝑥 + 11
