Question

Which of the following algebraic expressions are polynomials?

$3p^2-2p+1$

Answer 1

Given: $3p^2-2p+1$$=3p^2-2p^1+1p^0$

An algebraic expression can be called a polynomial if the power of terms of the expression is whole numbers. It should not be a radical power or a negative integer.

Here the power of expression is $2,1\mathrm{and}0$

Since all the powers are whole numbers.

Hence, $3p^2-2p+1$ is a polynomial.
