Question

simplify
(y-8)/(y-9) - (y+1)/(y+9) + (y-27)/(y^2-81)
please put the steps, i am not quite sure where to start on this one, thanks!

Answer 1

write y2 -81 = (y-9)(y+9) and this will be the denominator common

Answer 2

hence you need multiply the first term by (y+9) second by (y-9) and after calcule the numerator
