Question

A polynomial of degree ________ is called a quadratic polynomial

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is B $2$

The general form of quadratic polynomial is $p\left(x\right)=a{x}^2+bx+c$ where $x$ is a variable and $a,b,c$ are constants. The first term of this polynomial has power $2$ and the second term of this polynomial has power $1$ and therefore, the degree of the polynomial is the largest exponent that is $2$.

Hence, a polynomial of degree $2$ is called a quadratic polynomial.
