    the constant is just the number eg: 2x+1 : 1 is the constant

    coefficient of the term 14z: it is the number before the letter example: 6c the coefficient is 6

    @mathway Please explain the constant.

    The constant is just a number. It has no letter beside it. Please refer to my previous reply for an example.

    So the constant would be 18?

    -18. Don't forget the sign.

    Oh, okay! So the coefficients are 4, 11, 14..? (:

    4w + x – 11y + 14z – 18 "the coefficients are 4, 11, 14." The coefficient of 4w is 4. Yes! The coefficient of -11y is not 11. The coefficient of 14z is 14. Yes! What is the coefficient of x?

    Mmm.. either none or -18.

    None?

    No. It's not none. If I have \(\huge y\). It means \(\huge 1y\). So the coefficient is 1.

    -18 is your constant!

    If it's none, then it shouldn't be in the expression because it is 0.

    Also, so if it is a negitive number it doesnt count as a coefficient?

    It could be a coefficient. That 's why I said, "the coefficient of -11y is not 11" because you forgot to put the sign.

    Oh, okay. So a term is a number or letter?

    Yes. A term could be \(\huge6z, 9, -11xy, 99s^2,... \)
