Simplifying the Expression (6a² + 3a) - (4a² + 2a)
This expression involves combining like terms, which are terms with the same variable and exponent.
Step 1: Distribute the negative sign
Remember that subtracting an expression is the same as adding its opposite.
(6a² + 3a) - (4a² + 2a) becomes (6a² + 3a) + (-4a² - 2a)
Step 2: Combine like terms
- Combine the a² terms: 6a² - 4a² = 2a²
- Combine the a terms: 3a - 2a = a
Step 3: Write the simplified expression
The simplified expression is 2a² + a.
Therefore, (6a² + 3a) - (4a² + 2a) simplifies to 2a² + a.
