Question

In $15-x^2$, the term which is not a constant is __________ and its coefficient is ________.

• A. $-x^2$
• B. $-1$

Answer 1

Here, $15-x^2$ has two terms $15$ and $-x^2$.

From these two terms, $15$ is the constant as its value does not change.

So, the term which is not a constant is $-x^2$.

Its coefficient is $-1$, as the number multiplied to the variable of a term is the coefficient of that term.

Hence, In $15-x^2$, the term which is not a constant is $-x^2$ and its coefficient is $-1$.
