  1. How do you find the reciprocal of a polynomial? Find its multiplicative inverse To find the reciprocal of Polynomial A, divide the number 1 by Polynomial A Ex: 2x - 1 -5x2 + 3x - 1 6.3.2 Polynomials and Negative Powers

  2. How do you divide by a polynomial? Guided Practice p.285 (1-6) Multiply by the reciprocal of that polynomial

  3. Reminder:reciprocals can be written as negative exponents Ex: Simplify 2-3 2x  (3y)-1 6b3  (3ab)-2 Rule of negative exponents

  4. Ex: (a+b)(b-c)-1 (m-c)(m+c)(m-c)-1 (x-1)-1(x+1)-1 This rule applies to polynomials as well!
