Adding/Subtracting Polynomials

• Adding: Drop the parentheses and combine like terms

• Subtracting: CHANGE the signs on all the terms in the second polynomial. Then combine like terms

• *Remember: Like terms have the same variable AND the same exponent.

Multiple Choice

(3- 2x + 2x²) - (4x -5 +3x²)

• x_² + 6x + 8
• 2x² + 5x - 7
• -x² -6x + 8
• -2x² + 11x - 4

Multiple Choice

Find the sum.
