Question

State whether the given algebraic expression is polynomial? Justify.
$2m^2+7m-5$

Answer 1

An algebraic expression in which the variable involved have only non-negative integral powers is called a polynomial.

Here

$2m^2+7m-5=2m^2+7m^1-5$ is a polynomial

Because the variable m has exponent 2 in first term and exponent 1 in second term which is a non-negative integer.
