Question

In $y^2-3y+8x$, the numerical coefficient of $8x$ is __________.

Answer 1

A fixed number that is multiplied to the variable of a term is called the numerical coefficient of that term.

In $y^2-3y+8x$, there are $3$ terms $y^2,-3y\mathrm{and}8x$.

In the term $8x$, $8$ is multiplied to $x$.

Hence, $8$ is the numerical coefficient of $8x$.

Therefore, In $y^2-3y+8x$, the numerical coefficient of $8x$ is $8$.
