  2. Polynomials R.3 Adding Polynomials ▪ Subtracting Polynomials▪ Multiplying Polynomials ▪ Dividing Polynomials

  3. Like Terms Like Terms 4x 3 and x 3 5b and 8b 10a 2 and 3a 2 5x 4y 5 and 2x 4y 5 Not Like Terms 4x 3 and x 2 5b and 8ab 10a 2 and 2a 10 5x 5y 4 and 2x 4y 5 Like terms are terms with the same variables each raised to the same powers. To add or subtract polynomials, add or subtract the coefficients of like terms.

  4. Squaring a Binomial

  5. Multiplying Polynomials • Multiply Technique #1: Distribution

  6. Multiplying Polynomials • Multiply Technique #2: Box Method I do not have a preference as to which methodyou use; you may use whichever is easiest foryou.

  7. Multiplying Polynomials • Find the product. Multiply the parentheses first. Then distribute.

  8. Dividing Polynomials One term in the denominator Create separate fractions and simplify.

  9. Dividing Polynomials

  10. Dividing Polynomials More than one term in the denominator Use long division.

  11. Dividing Polynomials

  12. Dividing Polynomials Placeholders for missing terms Stop! The degree of the remainder (1) Is less than the degree of the divisor (2).
