What is the simplified form of 6a + 4 - 2a?

• A. 4a + 4
• B. 8a + 4
• C. 8a - 2
• D. 2a + 4

Answer: (A)

To find the simplified form of the expression 6a + 4 - 2a, the first step is to identify and combine the like terms. In this expression, the like terms are the terms that contain the variable 'a'.

Start with the terms involving 'a':

• You have 6a and -2a. When you combine these, you subtract 2a from 6a:

6a - 2a = 4a.

Next, you add the constant term, which is +4, to the result you've calculated from the variable terms. This gives you:

4a + 4.

Therefore, the entire simplified expression is 4a + 4. This corresponds to the correct answer, which accurately reflects the combination of like terms and the incorporation of the constant without altering their values.

In summary, the process of combining like terms focused on simplifying the variable parts leads to the correct simplified form.
