Polynomials consist of variables, constants and exponents.
[tex]\mathbf{\frac{6x - 1}{6x}}[/tex] is not a polynomial.
The expression is given as:
[tex]\mathbf{\frac{6x - 1}{6x}}[/tex]
Split
[tex]\mathbf{\frac{6x - 1}{6x} = \frac{6x}{6x} - \frac{1}{6x}}[/tex]
Simplify
[tex]\mathbf{\frac{6x - 1}{6x} = 1 - \frac{1}{6}x^{-1}}[/tex]
