Answer :
Final answer:
The greatest common factor for 30x^2 and 45x^5 is 15x^2.
Explanation:
The greatest common factor (GCF) for 30x2 and 45x5 can be found by identifying the common factors and choosing the highest power of each factor.
First, factorize both expressions:
- 30x2 = 2 × 3 × 5 × x × x
- 45x5 = 3 × 3 × 5 × x × x × x × x × x
The common factors are 3, 5, and x2. The highest power of 3 is 3, the highest power of 5 is 1, and the highest power of x is 2. Therefore, the GCF is 3 × 5 × x2, which simplifies to 15x2.
