Answer:
x^3 - 2x^2 + x - 10
Explanation:
Combine like terms in the first parenthesis:
Start with the expression x^3 - 2x^2 - 12. This means we look for terms with the same powers of x and combine them. In this case, there are no like terms to combine.
Combine like terms in the second parenthesis:
In the second parenthesis, we have x + 2. Since these terms don't share the same power of x, we leave them as they are.
Combine the simplified expressions from steps 1 and 2:
Now, combine the results from steps 1 and 2. We take the x^3 - 2x^2 - 12 from the first parenthesis and add it to the x + 2 from the second parenthesis.
The final expression is x^3 - 2x^2 + x - 10. This is achieved by combining like terms and maintaining the original terms that don't have common powers of x.
So, the step-by-step process results in x^3 - 2x^2 + x - 10.
