Math Problem Statement
Solution
I can see the question asks to perform polynomial operations with two given functions, and , and there are three different operations to evaluate:
Let's solve each of these step by step.
1.
To find , we simply add the two functions: Now, combine like terms: So, .
2.
For , subtract the two functions: Distribute the negative sign: Now, combine like terms: So, .
3.
Now for the multiplication : We'll distribute each term in by each term in : Now calculate each product: The resulting expression in descending order of powers is: So, .
Let me know if you'd like more details or if you have any questions! Here are some related questions for further exploration:
- What happens if you add or subtract two polynomials with different degrees?
- How would the expression change if one of the polynomials was a cubic function?
- How do you apply the distributive property in polynomial multiplication?
- Can polynomials of higher degree always be combined in operations like addition or subtraction?
- How would you graph the sum and difference of these functions?
Tip: Always double-check the combination of like terms in polynomial addition and subtraction to avoid mistakes in the final expression.
