What is the simplified form of 3a + 5a - 2a?

Explanation:
Combine like terms by adding their coefficients. All three terms share the same variable a, so you add 3, 5, and subtract 2: 3 + 5 − 2 = 6. This gives 6a. You can also see it by factoring out a: (3 + 5 − 2)a = 6a. The other results would come from missing or miscounting a term or its sign, but the correct simplification is 6a.
