Steps for Long Division Write the dividend in standard form, including terms with a coefficient of 0. Write division in the same way you would when dividing numbers. Multiply the answer by the divisor and then subtract Subtracting involves multiplying by -1 Repeat process until it can not be done Leftover is remainder; (Just like division) 7/8/2019 7:10 PM 6-3: Dividing Polynomials

6-3: Dividing Polynomials Example 1 Divide using Long Division (x2 – 5x + 4) ÷ (x – 1) 7/8/2019 7:10 PM 6-3: Dividing Polynomials

6-3: Dividing Polynomials Example 2 Divide (4x2 + 3x3 + 10) ÷ (x – 2) using long division 7/8/2019 7:10 PM 6-3: Dividing Polynomials
