Question

Which of the following statements is TRUE/CORRECT about Quadratic Equations? A quadratic equation is _____

• A. An expression with a single variable and degree $2$.
• B. An equation with a single variable and degree $2$.
• C. An equation with degree $2$ only.
• D. An equation with single variable only.

Answer 1

Answer: (B)

An equation with a single variable and degree $2$.

The definition of a Quadratic Equation states that an equation with one variable and degree $2$ is a Quadratic Equation. Only option $b$ satisfies the two basic conditions of a quadratic equation i.e. one/single variable and degree $2$. Hence $b$ is the correct answer.
