Review Polynomial Operations and Factoring

Add the polynomials.

(2x + 5y) + (3x - 2y)

• 3x + 5y

• 5x + 3y

• 5x + 7y

• 7xy + 1xy

Find the sum.

(5 + 3x) + (x - 12) =

• 4x + 7

• 4x - 7

• 7x - 4

• 4x - 17

Terms in a polynomial are separated by

• A. Parenthesis

• B. Multiplication/Division

• C. Constant

• D. Addition/Subtraction

Factor
10x² + 15x-5
