    what are the degrees of the top and bottom?

    -1 and 1 do you recall your rules for degrees?

    What do you mean by degree? You mean power of x?

    might only work for proper polynomilas tho simplify by multiplying top and bottom by 5x

    or we could use L'hospitals rule right?

    Or just the definition of the derivative.

    the fractiony top part tends to play havok with derivatives, but its worth a shot if you are allowed to use it

    1/x derives to -1/x^2 ... and the limit thing is usually x to 0 tho

    By looking at it, how did you come up to multiply by 5x?

    /x and /5 have 5x as a common denomto clear the fractions

    For \(h\to0\), where \(h\) represents the difference between two values of the independent variable. You can make a small modification to that definition to arrive at the derivative at a point: \[f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}~~\implies~~f'(c)=\lim_{x\to c}\frac{f(x)-f(c)}{x-c}\]
