Final answer:
The polynomial 3k² + 2k consists of two terms.
Step-by-step explanation:
The number of terms in the polynomial 3k² + 2k is two. A term in a polynomial is a product of numbers and variables that are separated by either a plus sign (+) or a minus sign (−). In this case, 3k² is the first term, and 2k is the second term. When identifying terms we look for parts of the expression that are added or subtracted from each other. The given polynomial is a simple one with just two terms.
