Simplify the polynomial.

–3f^2 + 4f – 3 + 8f^2 + 7f + 1

5f^2 – 11f + 2

11f^2 + 11f + 2

5f^2 + 11f – 2

–5f^2 + 11f – 2

3. (2x2 + 6x + 1) + (–7x2 + 2x – 3)

5x2 – 4x – 2

–5x2 + 8x – 2

5x2 – 8x + 2

–9x2 – 8x + 2

4. (3x2 – 7x – 4) – (6x2 – 6x + 1)

–3x2 – x –5

–3x2 –13x + 5

9x2 – x + 5

3x2 – 13x – 5

6. The area of room A is (5x^2– 7x – 6) ft^2. Room B has an area of (8x^2 + 6x – 1) ft^2. If room A is the larger room, how much greater is the area of room A than the area of room B?

–3x^2 – x – 7

13x^2 – 13x – 7

–3x^2 – 13x – 5

3x^2 – x – 5

My answers:

2. 5f^2 + 11f + 2

3. 5x2 – 8x + 2

4. –3x2 – x –5

6. -3x^2-13x-5

- Math help please ASAP -
