Question

Classify the following polynomials as linear, quadratic and cubic polynomials:

$2x$

Answer 1

Linear Polynomial:

A polynomial of degree one is called a linear polynomial. Its general form is $p\left(x\right)=ax+b$,where $a\ne 0$. For example, $2x+1$.

Here, the degree of the given polynomial is one.

Hence, the given polynomial is a linear polynomial.
