5.2 Dividing Polynomials
Example 1: Dividing by a monomial
Polynomial Long Division- Same format as dividing numbers. Use FILLERS for standard form! Example 2: Divide x3 – 4x2 + 8 by x – 1
Example 3 • Simplify: (4x2 – 8x – 7)(2x – 3)–1
Example 4: a. (y4 + 2y2 – y + 5) divided by (y2 – y +1)
Synthetic Division • - Used when divisor is in the form x – k. • - Polynomial must be in standard form. Use FILLERS if terms are • missing. • - Create a polynomial out of coefficients that are left under the line. • - The power of the first term is one less than the degree of the dividend. • - The final number is the remainder. Example 5: a. x3 – x2 –2x + 8 by x – 1
Example 6: Find the Remainder 2x3 + 13x – 7 by x + 6
Example 7: Simplfiy. (4y4 – 6y2 + 4y – 1) (y – 2)-1
