Simplifying Polynomial Expressions
This article will walk through the process of simplifying the expression (-3p^3+5p^2-2p)+(-p^3-8p^2-15p).
Understanding Polynomials
A polynomial is an expression consisting of variables and coefficients, combined using addition, subtraction, and multiplication. Each term in a polynomial consists of a coefficient and a variable raised to a non-negative integer power.
Simplifying the Expression
-
Identify Like Terms:
- p^3 terms: -3p^3 and -p^3
- p^2 terms: 5p^2 and -8p^2
- p terms: -2p and -15p
-
Combine Like Terms:
- p^3 terms: -3p^3 - p^3 = -4p^3
- p^2 terms: 5p^2 - 8p^2 = -3p^2
- p terms: -2p - 15p = -17p
-
Write the Simplified Expression: The simplified expression is -4p^3 - 3p^2 - 17p.
Conclusion
By identifying and combining like terms, we have successfully simplified the polynomial expression (-3p^3+5p^2-2p)+(-p^3-8p^2-15p) to -4p^3 - 3p^2 - 17p. This process is essential for solving equations, evaluating expressions, and understanding the relationships between different polynomial expressions.
