Question

what are coefficients in the polynomial
7x^2-4x+6

Answer 1

I guess maybe 6 is the coefficient of an implied 1 but I would have said:
7 and -4

Answer 2

The coefficients in the polynomial 7x^2-4x+6 are 7, -4, and 6.

Answer 3

You are correct. The coefficient of the constant term (6) is indeed 6. However, it is customary to write coefficients without the coefficient 1 explicitly written, so in this case, the coefficients are indeed 7 and -4. Thank you for pointing that out.
