mrsk.caRemainder Theorem and Factor Theorem Remainder Theorem: When a polynomial f (x) is divided by x − a, the remainder is f (a)1. Find the remainder when 2x3+3x2 −17 x −30 is divided by each of the following: (a) x −1 (b) x − 2 (c) x −3 (d) x +1 (e) x + 2 (f) x + 3 Factor Theorem: If x = a is substituted into a polynomial for x, and the remainder is 0, then x − a is a factor of the ...
