Unit 1 Day 4 Notes Combining Like Terms Examples: 1. 𝟒(𝟕𝒙 − 𝟖) + 𝟔(𝟓𝒙 + 𝟏𝟎)

2. 𝟒(𝟔𝒙𝟑 – 𝟒𝒙𝟐 + 𝟏𝟏) – 𝟕(𝟓𝒙𝟐 + 𝟗)

3. 𝟏𝟒

(𝟒𝒙𝟐𝒚𝟐 + 𝟓𝒙𝒚𝒛 + 𝟑𝒙𝟐𝒚𝟐 − 𝒙𝒚𝒛 + 𝒙𝟐𝒚𝟐)

4. 𝟏𝟓

(𝟑𝒚𝒛 + 𝟒(𝟐𝒚𝒛 − 𝟑𝒚 + 𝒚𝒛 − 𝟕𝒚))

On Your Own: 1. 𝟐𝒖𝒗 − 𝟑(𝒖𝒗 + 𝒖𝟐𝒗𝟐)𝟒(𝒖𝒗 − 𝒖𝟐𝒗𝟐)

2. 𝟗𝒙𝟑𝒚𝟑 − 𝟑𝒙𝒚 + 𝟕𝒙𝟑𝒚𝟑 − 𝒙𝒚 − (𝟐𝒙𝒚)𝟑

3. 𝟕𝒎 − 𝟗𝒏𝟐 − (−𝟑𝒏𝟐 + 𝟖𝒎 + 𝟏) + 𝟏𝟓

4. 𝟏𝟐

(−𝟗𝒑𝟐𝒒𝟐𝒓𝟐 + 𝟕𝒒𝒓𝟒 − 𝟑𝒑𝟐𝒒𝟐𝒓𝟐 − 𝟓𝒒𝒓𝟒)

Evaluating Expressions Examples: Use the following to evaluate the expressions: 𝒙 = −𝟔 𝒚 = 𝟑 𝒛 = 𝟏𝟐 1. 𝟒𝒙 − 𝟐 + 𝟓𝒙 + 𝟕 − 𝟐𝒙

2. 𝟏𝟎𝒙 − 𝟒𝒚 + 𝟑𝒙𝟐 + 𝟐𝒙 − 𝟐𝒚

3. 𝟒𝒙𝒛 − 𝟐𝒙𝟐𝒚 + 𝟓 − 𝒙𝒛 + 𝒙𝒚𝟐 + 𝟐𝒙𝟐𝒚 + 𝟒

4. 𝟓𝒙𝒚 + 𝟐𝒛 + 𝟕𝒚 − 𝟐𝒚𝒙 + 𝟑𝒛

On Your Own: Use the following to evaluate the expressions: 𝒙 = −𝟔 𝒚 = 𝟑 𝒛 = 𝟏𝟐 5. 𝟐𝒚𝒛 − 𝟑(𝒙𝒛 + 𝒙𝟐𝒚𝟐) − 𝟒(𝒚𝒛 − 𝒙𝟐𝒚𝟐)

6. 𝟗𝒙𝒚𝟑 − 𝟑𝒙𝒛 − 𝟓𝒙𝒚𝟑 − 𝒛𝒙 − (𝟐𝒙𝒚)𝟑
