Answer:
B. 1/2 and 1.
Explanation:
The coefficient of a variable is the number that the variable is being multiplied for. In this example. We can see that x² is being multiplied by 1/2, therefore 1/2 is one of the coefficients.
In the case of x, it doesn't have a number before it, it means that it's being multiplied by 1. Hence, our second coefficient is 1.
