please make sure u write the equation correctly since im having to guess what it looks like
according to how you inputted the equation this is what it would look like
z-%284%2Fz%29-5-z%2B%281%2Fz%29%2B5%2Bz%28-15%2Fz%5E2%29-25


however im pretty sure u meant this:
factor


common denom


add fractions


foil
