MCQ
A polynominal in the following is:
- A$7{\text{x}}^2-5\sqrt{\text{x}}+5$
- ✓${\text{t}}^3-2{\text{t}}+1$
- C$\text{x}^2-\dfrac{1}{\text{x}^2}$
- D$\sqrt{\text{y}}+5\text{y}-1$
Degree of variables in ploynomials $(1), (3)$ and $(4)$ are not whole numbers.
$\therefore$ they are not ploynomials. While in option $(2)$ degrees of variable are whole numbers.
$\therefore$ it is a ploynomial.
