MCQ
Which of the following is a linear polynomial$?$
- A$x + x2$
- ✓$x + 1$
- C$5x^2 - x + 3$
- D$\text{x}+\frac{1}{\text{x}}$
✓
Answer
Correct option: B.
$x + 1$
A polynomial of degree $1$ is called a linear polynomial.
Options $(a),$ and $(c)$ have degree $2,$
so ther are quadratic polynomials.
option $(d)$ has a negative power, so it is not a polynomial.
The degree of $x + 1$ is $1,$ so it is a linear polynomial.
