Answer 1

Answer:

-3/2

Step-by-step explanation:

1/u+1 + 2/u+2 = 5/u+4

1(u+2)/(u+1)(u+2) + 2(u+1)/(u+1)(u+2) = 5/u+4

u+2+2u+2/(u+1)(u+2) = 5/u+4

3u+4/u^2+3u+2 = 5/u+4

(3u+4)(u+4) = 5(u^2+3u+2)

3u^2+16u+16 = 5u^2+15u+10

-2u^2+u+6 = 0

2u^2 - u - 6 = 0

(2u + 3)(u - 2) = 0

Since, u is not equal to 2 (given),

u = -3/2

Hope this helps you!
