Look for terms that are the same
2n + 5n²  n – 3n²
2n – n are alike5n²  3n² are alike
Add or Subtract the constants
2nn = (1)n 5n²  3n² = 2n²
List in order by exponents
Final answer: 2n² + n
Answer Box:
8x + 6n
7p
3n – 3n²
Z + 2z³
8x + 6n
6p + p
3n – 3n²
7z – 6z + 2z³
Identify the terms, variables, constants, and exponents in problems 2 and 4.
Why can’t some of these terms be combined?
