Question

The general form of a quadratic polynomial in the variable $x$ is:

• A. $a$
• B. $ax+b$
• C. $a{x}^2+bx+c$
• D. $a{x}^3+b{x}^2+cx+d$

Answer 1

The correct option is C $a{x}^2+bx+c$

The general form of a constant polynomial is $a$

The general form of a linear polynomial is $ax+b$

In general, polynomial is written with decreasing order of their exponents. As we have to write a quadratic, the highest power will be 2.

The general form of a quadratic polynomial is $a{x}^2+bx+c$

Therefore, option (c.) is the correct answer.
