Which of the following expressions are polynomials in one variable and which are not ? State reasons for your answer. $4 x^{2}-3 x+7$.
Which of the following expressions are polynomials in one variable and which are not ? State reasons for your answer. $4 x^{2}-3 x+7$.
$4 x^{2}-3 x+7$
$\Rightarrow 4 x^{2}-3 x+7 x^{0}$
$\because$ All the exponents of $x$ are whole numbers.
$\therefore $ $4 x ^{2}-3 x +7$ is a polynomial in one variable.
