 Algebraic Division

Algebraic division has the same algorithm, procedure, as regular division. DIVISION
 1st: Use a blank rectangular sheet of paper to separate the storage region from the display area and to create a border for the rectangular area. 2nd: Represent the divisor vertically in storage on the left edge of the display area. 3rd: Represent the dividend in the display area in descending order beginning with the upper left corner. 4th: Arrange, if possible, the dividend in IDENTICAL rows in the display area. Matching one row per vertical divisor tile leaves remainders extra in the storage area. 5th: Once a single rectangular arrangement of tiles (extra remainder tiles excluded) is created, represent the appropriate quotient horizontally in the storage area as dictated by the dividend. 6th: If a single rectangular arrangement of tiles is not possible, add zeros as needed to fill the required area. 7th: Read the quotient and the remainder.

The work and answer for each of these problems is shown below and individually through the arrow.

 ex. 1. Divide 4x-12 by 4. ex. 5. Divide (xý - 4x + 3) / (x-1) ex. 2. Divide (xý+x) ¼ x ex. 6. Divide xý - x - 6 by x-3. ex. 3. Divide (2x°+6xý-2x+1) / (2x)  ex. 7. Divide xý + 7x - 11 by x-5. ex. 4. Divide (xý + 4x + 3) / (x+3)            www.termtiles.com, Unit 18   © 2008, A. Azzolino
