Question

This exercise involves addition and subtraction when denominators are the same. Simply the result of possible.

Answer 1

Given the shown expression

`(y^2)/(y^2-25)+(25-10y)/(y^2-25)`

simplifying

`(y^2+25-10y)/(y^2-25)`
`(\left(y-5\right)^2)/(y^2-25)`
`(\left(y-5\right)^2)/(\left(y+5\right)\left(y-5\right))`
`(\left(y-5\right)\left(y-5\right))/(\left(y+5\right)\left(y-5\right))`
`(y-5)/(y+5)`
