To factor the polynomial x³ + 12x² + 2x + 24 by grouping, we can follow these steps:
- First, we group the terms in pairs: (x³ + 12x²) and (2x + 24).
- Next, we factor out the greatest common factor (GCF) from each group:
- From the first group, x² is the GCF, so we factor it out:
- x²(x + 12)
- From the second group, 2 is the GCF, so we factor it out:
- 2(x + 12)
- Now our expression looks like this:
- x²(x + 12) + 2(x + 12)
- Notice that (x + 12) is a common factor in both terms, so we can factor that out:
- (x + 12)(x² + 2)
- Thus, the complete factorization of the polynomial x³ + 12x² + 2x + 24 is:
- (x + 12)(x² + 2)
In conclusion, we used the method of grouping to successfully find the factors of the given polynomial. Factoring allows us to rewrite the polynomial in a product form, which can be useful for solving equations or analyzing the behavior of the function.
