Problem
Solution
For this case we can take common factor in the denominator 2x and we got:
[tex]\frac{1}{2x}(\frac{3}{1}-\frac{1}{4x})[/tex]Then we can solve the fractions with this operation:
[tex]\frac{1}{2x}(\frac{3\cdot4x-1\cdot1}{1\cdot4x})=\frac{1}{2x}(\frac{12x-1}{4x})[/tex]then we can simplify on this way:
[tex]\frac{12x-1}{6x^2}[/tex]
