What is the cofficents in the expression 3x-4y+2

Question

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

Answer 1

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 ax² + 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.

Answer 2

Simply put, the coefficients are the numbers in front of the variables. In this problem, we have two variables, or unknown quantities. They are x and y. The coefficients of these two variables are 3 and 4, respectively. The number 2 is the constant term in this expression.

Answer 3

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
