- 9. Example 2: What isthe sum of (2b + 5c) and (4b + 8c) ? Method 2: Add horizontally Group like terms and add the numerical coefficients e up similar terms, then add the numerical coefficients.
- 10. Perform the indicatedoperation. a. 4x + 5x = ______ b. -4x + 5x = ______ c. (4x + 5x) + (4y – (–5y)) = ____ + 9y d. (6n2 + 4n – 2) + (–3n + 8) = ______
- 11. Directions: Translate eachillustration into algebraic expression and write the sum on the third column.
- 12. Rules for AddingPolynomials • To add polynomials, simply combine similar terms. • To combine similar terms, get the sum of the numerical coefficients and annex the same literal coefficients. • If there is more than one term, for convenience, write similar terms in the same column. REMEMBER!
