Coefficient

Example:

$3x^2-5xy+y^2+0.2x+39$

Here, the coefficient of the $x^2$ term is $3$ .

The coefficient of the $xy$ term is $-5$ .

The coefficient of the $y^2$ term is $1$ (note that the number 1 need not be written).

The coefficient of the $x$ term is $0.2$ .

The coefficient of the $y$ term is $0$ (since the $y$ term doesn't show up at all).
