Your are missing parentheses if you mean $$\large \frac{f^2-25}{5}\times\frac{f}{f-5}$$ which should have been written (f^2-25)/5 * f/(f-5) according to mathematical conventions (PEMDAS)

hint: factor and cancel common factors. make sure to insert condition that the cancelled factor does not equal zero.
