^{2}+ bx + c, "x" is a variable, and "a" and "b" are coefficients.

I'm not sure what coefficients mean I tried looking it up but the description for it was very confusing to me.

Tutors, sign in to answer this question.

Coefficient is a number used to multiply a variable. for example 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. Suppose if you see only x, it's actually 1x. Sometimes a letter stands in for the number. For example: In ax^{2} + bx + c, "x" is a variable, and "a" and "b" are coefficients.

Here,

In the expression 3x-4y+2, we see three terms 3x, -4y, 2

Terms are composed of coefficient and a variable

In 3x, 3 is the coefficient and x is the variable

In -4y, -4 is the coefficent and y is the variable

In 2, there's no variable, so it is a special term called a constant.

Coefficient can be whole number, positive or negative, fraction, decimal etc.

Coefficients are the numbers that are multiplied by the variables (x, y, z etc.)

So..

3 is the coefficient of x

-4 is the coefficient of y
