Quotient: 2. x 5 10x x 1, x Quotient: 3. 12x 3 + 5x x 7, x Quotient: 4. 8x 3 4x x 3, x Quotient: 5. 2x 5 3x 4 5x 2 10, x 4 5. Quotient: 6. x 6 1, x Quotient:
2 Use Synthetic Division and the Remainder Theorem to find P(c). 7. P (x) = 2x 3 x 2 + 3x 1, c = 3 7. Remainder with Synthetic Division: Remainder with the Remainder Theorem: 8. P (x) = 6x 3 x 2 + 4x, c = 3 8. Remainder with Synthetic Division: Remainder with the Remainder Theorem: 9. P (x) = x x 2 1, c = 4 9. Remainder with Synthetic Division: Remainder with the Remainder Theorem: 10. P (x) = x 3 + 3x 2 + 5x + 30, c = Remainder with Synthetic Division: Remainder with the Remainder Theorem: Use Synthetic Division and the Factor Theorem to determine whether the given binomial is a factor of P(x). 11. P (x) = x 3 + 4x 2 27x 90, x P (x) = 3x 3 + 4x 2 27x 36, x P (x) = 16x 4 8x 3 + 9x x + 4, x P (x) = x 5 + 2x 4 22x 3 50x 2 75x, x 5 14.
