Question

Degree of the polynomial $4x^2+x+5$ is

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is B

2

Note that the given polynomial is a polynomial in one variable, that is, $x$.

We know that the degree of a polynomial in one variable is the greatest of the exponents of its various terms.

The given polynomial consists of three terms, namely, $4x^2$, $x$ and $5$.

The exponent of the term $4x^2$ is 2, the exponent of the term $x$ is 1 and the exponent of the term $5$ is 0.

Hence the degree of the given polynomial is 2.
