Final answer:
To find the GCF of the terms in the polynomial 15x² + 18, we factor each term and identify the common factors. The GCF is the largest shared factor, which in this case is 3. Therefore, the GCF of the polynomial is 3.
Step-by-step explanation:
To determine the greatest common factor (GCF) of the terms in the polynomial 15x²+ 18, we need to find the largest number that divides evenly into both 15x² and 18. We can start by factoring each term:
15x² can be factored as 3 * 5 * x * x, while 18 can be factored as 2 * 3 * 3. Since both terms have a factor of 3, the GCF of 15x² and 18 is 3. Therefore, we can write the polynomial as 3(5x² + 6).
