Question

Any equation of the form p(x) = 0, where p(x) is a polynomial of degree 2 is called

• A. linear equation in one variable
• B. linear equation in two variables
• C. quadratic equation
• D. None of these

Answer 1

The Correct Option is C

Correct answer: quadratic equation

Explanation: 
An equation of the form \( p(x) = 0 \), where \( p(x) \) is a polynomial of degree 2, is called a quadratic equation. 
The general form of a quadratic equation is:
\[ ax^2 + bx + c = 0,\quad \text{where } a \ne 0 \]

Linear equations are of degree 1, not 2. So, the other options are incorrect.
