Answer 2

To solve the expression 64 - (2 + x)³, we can follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Let's break down the steps:

1. Simplify the expression inside the parentheses: (2 + x) - There are no like terms to combine, so we leave it as is.

2. Evaluate the exponent: (2 + x)³ - To simplify this, we need to cube the expression (2 + x). - The cube of a binomial can be expanded using the formula (a + b)³ = a³ + 3a²b + 3ab² + b³. - Applying this formula, we get: (2 + x)³ = 2³ + 3(2)²(x) + 3(2)(x)² + x³. - Simplifying further, we have: (2 + x)³ = 8 + 12x + 6x² + x³.

3. Substitute the simplified expression back into the original expression: 64 - (2 + x)³ - Now we can substitute the simplified expression (8 + 12x + 6x² + x³) back into the original expression. - We get: 64 - (8 + 12x + 6x² + x³).

4. Simplify the expression inside the parentheses: (8 + 12x + 6x² + x³) - There are no like terms to combine, so we leave it as is.

5. Evaluate the subtraction: 64 - (8 + 12x + 6x² + x³) - To subtract a group of terms, we distribute the negative sign to each term inside the parentheses. - We get: 64 - 8 - 12x - 6x² - x³.

6. Combine like terms: 64 - 8 - 12x - 6x² - x³ - There are no like terms to combine, so we leave it as is.

Therefore, the simplified expression is 64 - 8 - 12x - 6x² - x³.
