Question

Perform the indicated operation.(4r/r+3) - (5/r)

Answer 1

4r² - 5r - 15 / r(r+3)

Explanation:

To solve this problem, we will proceed the following way, writing down the common multiple of the denominators.

`(4r)/(r+3) -(5)/(r) =(4r(r)-5(r+3))/(r(r+3)) =(4r^(2)-5r-15 )/(r(r+3))`

Thus, the answer is 4r² - 5r - 15 / r(r+3)
