A1-1.2- A.10A Adding and Subtracting Polynomials

• 6x + 5

• 2x + 1

• 2x - 1

• 6x - 1

Answer explanation

To combine like terms in 4x - 3 + 2 - 2x, first combine the x terms: 4x - 2x = 2x. Then combine the constants: -3 + 2 = -1. Thus, the final expression is 2x - 1, which matches the correct answer.

• 3x – 2

• 11x – 2

• 11x + 8

• 11x – 8

Answer explanation

To simplify (7x + 3) + (4x - 5), combine like terms: 7x + 4x = 11x and 3 - 5 = -2. Thus, the expression simplifies to 11x - 2, which is the correct answer.

• 3x – 5

• 3x – 9

• 7x – 5

• 7x – 9

• –2x + 13

• –2x + 15

• 16x + 13

• 16x + 15

Answer explanation

To simplify (7x + 14) - (9x - 1), distribute the negative: 7x + 14 - 9x + 1. Combine like terms: (7x - 9x) + (14 + 1) = -2x + 15. Thus, the correct answer is –2x + 15.

• 5x – 9y

• 6x + y

• 6x + 20y

• 6x² + 20y²

• 2x – 6

• 2x

• 2x² – 6

• 2x²

• x² – 3x – 3

• x² – 3x + 3

• x² – 3x + 13

• 7x² – 3x + 13

Answer explanation

To simplify (4x² - 3x + 8) - (3x² - 5), distribute the negative sign: 4x² - 3x + 8 - 3x² + 5. Combine like terms: (4x² - 3x²) + (-3x) + (8 + 5) = x² - 3x + 13. Thus, the correct answer is x² – 3x + 13.

• 4x

• 4x – 10

• 4x²

• 4x² – 10
