Answer
See the answer below.
Work Step by Step
A polynomial can be represented as $p_1x^n+p_2x^{n-1}+....+p_n=0$; where $p_1,p_2,...,p_n$ are real numbers and the power of $x$ will be non-negative integers.
Power of $x$ shows the highest exponent or higher degree.For a linear polynomial degree should be $1$ whereas for a quadratic polynomial degree should be $2$ .
