Simplifying Polynomial Expressions
This article will guide you through the process of simplifying the polynomial expression: (-3p^3 + 5p^2 - 2p) + (-p^3 - 8p^2 - 15p)
Understanding the Process
Simplifying polynomial expressions involves combining like terms. Like terms are terms that have the same variable and the same exponent. For example, 3p² and -5p² are like terms, while 3p² and 3p³ are not.
Step-by-Step Solution
-
Remove the parentheses: Since we are adding the two polynomials, the parentheses do not affect the order of operations. We can rewrite the expression as: -3p³ + 5p² - 2p - p³ - 8p² - 15p
-
Identify like terms: Now we identify the terms that have the same variable and exponent:
- p³ terms: -3p³ and -p³
- p² terms: 5p² and -8p²
- p terms: -2p and -15p
-
Combine like terms: We add the coefficients of the like terms:
- -3p³ - p³ = -4p³
- 5p² - 8p² = -3p²
- -2p - 15p = -17p
-
Final Expression: Combine the simplified terms to get the final expression: -4p³ - 3p² - 17p
Conclusion
Therefore, the simplified form of the polynomial expression (-3p³ + 5p² - 2p) + (-p³ - 8p² - 15p) is -4p³ - 3p² - 17p.
