The Chinese Remainder Theorem by Example – Teaching With Problems

WebExample 1: Find the remainder when p (x): 3x 5 − x 4 + x 3 − 4x 2 + 2 is divided by q (x): x − 1. Solution: We will use the remainder theorem. We will substitute the zero of q (x) into the polynomial p (x) to find the remainder r. The zero of q (x) is x = 1. So the remainder, r = p (1) = 3 (1) 5 - (1) 4 + (1) 3 - 4 (1) 2 + 2 = 3 - 1 + 1 - 4 + 2 = 1 the cheap car company https://sptcpa.com
