Adding Polynomials Simplify (6x2 + 3x + 7) + (2x2 – 6x – 4). Method 1: Add vertically. Line up like terms. Then add the coefficients. 6x2 + 3x + 7 2x2 – 6x – 4 8x2 – 3x + 3
Adding Polynomials Simplify (6x2 + 3x + 7) + (2x2 – 6x – 4). Method 2: Add horizontally. Group like terms. Then add the coefficients. (6x2 + 3x + 7) + (2x2 – 6x – 4) = (6x2 + 2x2) + (3x – 6x) + (7 – 4) = 8x2 – 3x + 3
Add 2x3 – 5x2 + 3x – 9 and x3 + 6x2 + 11. SOLUTION 2x3 – 5x2 + 3x – 9 edweb.tusd.k12.az.us/tbushnell/Int%20Alg/6.3%20a.ppt
EXAMPLE 2 Add 3y3 – 2y2 – 7y and –4y2 + 2y – 5. (3y3 – 2y2 – 7y) + (–4y2 + 2y – 5) = 3y3 – 2y2 – 4y2 – 7y + 2y – 5 = 3y3 – 6y2 – 5y – 5 edweb.tusd.k12.az.us/tbushnell/Int%20Alg/6.3%20a.ppt
