It is the coefficient of the unknown variable
37n
8x
Let the number be x and so the expression is 8x
4x
It is the coefficient of the variable
factor
That is often called the coefficient.
It is called the coefficient of the variable
The coefficient would be the number multiplied by the variable, in this case: 7
(x - 25)*4
x=unknown number So the expression would be: 4(x+3) The sum of a number (x) and 3, all multiplied by 4.
A number or expression that can be multiplied to get another number or expression is called a factor.
