How do you divide by a polynomial? Guided Practice p.285 (1-6) Multiply by the reciprocal of that polynomial
Reminder:reciprocals can be written as negative exponents Ex: Simplify 2-3 2x (3y)-1 6b3 (3ab)-2 Rule of negative exponents
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!
