Question

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

$5x^3-2x^2+3x-2$

Answer 1

Cubic Polynomial:

A polynomial of degree three is called a cubic polynomial. Its general form is $p\left(x\right)=a{x}^3+b{x}^2+cx+d$. For example, $7x^3+2x^2+5x+2$.

Here, the degree of the given polynomial is three.

Hence, the given polynomial is a cubic polynomial.
