Answer 2

A polynomial is one term or a sum of terms.

A term is one number or a number multiplied by one or more variables.

The number in a term is called coefficient.

Answer 3

if you see just a "letter", it is assumed to be multiplied by 1

example: x+2
the coefficient of x is 1, and you could write it as 1x + 2 (but nobody does)

Answer 4

there is nothing such as "there is no coefficent of the variable "
for variables there is three cases ( assume variable x with degre n)
case 1 :
when the coefficent of the variable = 0
\(\Huge \color{red}{0}x^n=0\)
case 2
when the coefficent of the variable = 1
\(\Huge \color{red}{1}x^n=x^n\)
case 3
when the coefficent of the variable = a s.t a any number
\(\Huge \color{red}{a}x^n\)
\(\large \color {green}{\text {so there is always would be a coefficent when there is a variable :D}} \)
