8 1 -- + -- add and simplify z z^2

OpenStudy (anonymous):

(8z + 1) / z^2

this cant be simplified any further

does the top need parentheses or not

OpenStudy (anonymous):

i always put parenthesis in cases like this because it could be interpreted as 8z + 1/2z. The whole top of the fraction is divided by 2z and the brackets clearly indicate this.
