MCQ
Which of the following is a polynomial in one variable?
- A$\text{x}^2+\text{x}^{-2}$
- ✓$\sqrt{2}-\text{x}^2+3\text{x}$
- C$\sqrt{2\text{x}}+9$
- D$\text{x}^2+\text{y}^8+9$
✓
Answer
Correct option: B.
$\sqrt{2}-\text{x}^2+3\text{x}$
$\sqrt{2}-\text{x}^2+3\text{x}$ is a polynomial in one variable $x$ and also the powers of each term is a whole number.
