Classify the following polynomial by degree and number term 3x+12

The degree of a polynomial is the highest power.        theis time its 1

The leading term is the one with the highest power.          3x

The leading coefficient is the coefficient (number in front) of the pronumeral with the highest power.   3

I haven't heard the expression number term before.  I suppose I might call it the independant term but it is 12

 

This is a simplistic view.  There is a mathsisfun web page that deals with this more fully :)

Each number term has degree 0 (zero).

Any term which has one or more variable has a degree equal to the number of variables; so, 3x has degree 1 (because there is one variable, the 'x').

Any expression with more than one term has a final degree equal to the degree of its highest degree term, so the expression 3x + 12 has degree 1.
