Multiplying Polynomials: (m+3)(m^2+3m+5)
This article will guide you through the process of multiplying the two polynomials: (m+3)(m^2+3m+5).
Understanding the Concept
To multiply polynomials, we use the distributive property. This means we multiply each term in the first polynomial by every term in the second polynomial.
Step-by-Step Solution
-
Expand the first polynomial: (m+3) remains as it is.
-
Expand the second polynomial: (m^2 + 3m + 5) remains as it is.
-
Multiply each term in the first polynomial by every term in the second polynomial:
- m * m^2 = m^3
- m * 3m = 3m^2
- m * 5 = 5m
- 3 * m^2 = 3m^2
- 3 * 3m = 9m
- 3 * 5 = 15
-
Combine like terms: m^3 + 3m^2 + 5m + 3m^2 + 9m + 15 = m^3 + 6m^2 + 14m + 15
Final Answer
Therefore, the product of (m+3)(m^2+3m+5) is m^3 + 6m^2 + 14m + 15.
