Identify the polynomial from the following:
  • A
    $4{\text{x}}-3 + 5{\text{x}}2 -5{\text{x}}$
  • ✓
    $\frac{2}{5}\text{x}^{2} - 7{\text{x}} +8$
  • C
    $\frac{4}{\text{x}^{2}} + \frac{5}{\text{x}} + 7$
  • D
    $3.5{\text{x}}^{7} - 8{\text{x}}^{6} + \dfrac{1}{5}{\text{x}}$
✓

Answer

Correct option: B.
$\frac{2}{5}\text{x}^{2} - 7{\text{x}} +8$

A polynomial is a mathematic expression containing several terms where the variables have positive integral exponents. $A$ and $C$ have negative exponents, so they are not polynomials. $B$ and $D$ are correct.
