    • January 13, 2010 Synthetic Division A Shortcut!!!!
    • January 13, 2010 When the divisor is binomial in the form x ± a we can use synthetic division in place of long division 1. Arrange the dividends terms in descending order of power. 2. If your binomial is x - a we will use the positive value for a If your binomial is x + a we will use the negative value for a because is represents x -(-a) 3. Organize your value for a and the coefficients as follows a coefficients in descending order 4. Use an algorithm to solve for the quotient and remainder
    • January 13, 2010 1. Arrange the dividends terms in descending order of power. 2. If your binomial is x - a we will use the positive We will use and example to value for a explain the algorithm If your binomial is x + a we will use the negative value for a because is represents x -(-a) 3 2 6x + 16x - 19x - 4 3. Organize your value for a and the coefficients as follows divided by a coefficients in descending order x-2 4. Use an algorithm to solve for the quotient and remainder
    • January 13, 2010 Use synthetic division to find the quotient and if possible a remainder
    • January 13, 2010 For each of the following find the quotient and if possible a remainder using both long and synthetic division methods, check to make sure you get the same answers 3 2 x + 2x - 5x - 6 ÷ (x - 3)
    • January 13, 2010 For each of the following find the quotient and if possible a remainder using both long and synthetic division methods, check to make sure you get the same answers 4 3 (x - 2x +5x + 2) ÷ (x + 1)
