A term is a number, variable or the product of a number and variable(s).
Here are some terms:
A constant term is a number.
A coefficient is the numeric factor of a term. A constant term is a special case of a coefficient. The coefficients of the terms below are highlighted in red:
The coefficient of x = 1x is 1 and the coefficient of -x = -1x is -1. The coefficient of is .
Two terms are called like terms
if they differ by a constant factor. That is, only their numerical coefficients
The following are like terms:
And these are like terms:
But none of the following are like terms:
as the power of x differs in the different terms.
