Question
Is the expression $4{x^2} - 3x + 7{\text{ }}$, polynomial in one variable or not$?$ State the reason for your answer.

Answer

$4{x^2} - 3x + 7{\text{ }}$
We can observe that in the polynomial $4{x^2} - 3x + 7{\text{ }}$
we have $x$ as the only variable and the powers of $x$ in each term are a whole number.
Therefore, we conclude that $4{x^2} - 3x + 7{\text{ }}$ is a polynomial in one variable.
