Distribute the negative sign: The negative sign in front of the parentheses means we multiply each term inside the second parentheses by -1.
(3a² + 1) - (4 + 2a²) = 3a² + 1 - 4 - 2a²
-
Combine like terms: Identify terms with the same variable and exponent, and combine their coefficients.
3a² - 2a² + 1 - 4
-
Simplify: Combine the coefficients of the 'a²' terms and the constant terms.
a² - 3
Final Answer
Therefore, the simplified form of the expression (3a² + 1) - (4 + 2a²) is a² - 3.
