Math 2 Name:______________________________ Unit 2A Day 3 Notes – Polynomial Operations Date:________________ Adding & Subtracting Polynomials: Examples: 1. (𝟗𝒚 − 𝟕𝒙 + 𝟏𝟓𝒛) + (−𝟑𝒚 + 𝟖𝒙 − 𝟖𝒛)

2. (𝟑𝒙𝟐 + 𝟑𝒙𝒚 − 𝒚𝟐) + (𝟒𝒙𝒚 + 𝟔𝒚𝟐)

3. (𝟕𝒂 − 𝟏𝟎𝒃) − (𝟑𝒂 + 𝟒𝒃)

4. (𝟑𝒚𝟐 + 𝟕𝒚 + 𝟖) − (𝟐𝒚𝟐 − 𝟒𝒚 + 𝟑)

5. (𝟑𝒙𝟑 − 𝟗) − (𝟐𝒙𝟑 + 𝟏)

6. (𝟑𝒙𝟐 + 𝒙 − 𝟗) − (𝒙𝟐 − 𝟐𝒙 + 𝟏)

7. Find the measure of the 3rd side of the triangle below if the perimeter is 𝟕𝒙𝟐 + 𝟏𝟏𝒙 + 𝟔.

8. Find the measure of the 4th side of the quadrilateral below is the perimeter is 𝟏𝟒𝒎+ 𝟔.
