Question

Classify the following polynomial as linear, quadratic, cubic and biquadratic polynomial:

$5z$.

Answer 1

Classifying the given polynomial:

Degree of polynomial: If a polynomial is in one variable, the highest power of the polynomial is called degree of polynomial.

Linear polynomial: A polynomial of degree one, is called linear polynomial.

The given polynomial is $5z$.

Clearly, here the highest power of variable i.e; $z$ is $1$. So, it is a linear polynomial.

Hence, $5z$ is a linear polynomial.
