Question

solve for u

u+1/u+7 +1 = u+2/u+1

Answer 1

first multiply by u+1 to get (u+1)^2/(u+7)+u+1=u+2

Answer 2

now multiply by u+7
(u+1)^2+(u+1)(u+7)=(u+2)(u+7)

Answer 3

now expand the brackets and but everything to one side and solve it

Answer 4

would the answer have a u in it or just numbers ?

Answer 5

just number(s), and there might be 2 answers

Answer 6

because i get u+3/2 idk how :-/

Answer 7

ok expanding gives
u^2+2u+1+u^2+u+7u+7=u^2+2u+7u+14

Answer 8

now putting everything to the left
u^2+u-6=0

Answer 9

do you know how to solve this?

Answer 10

wait let me try it give me a sec

Answer 11

its all to the left so wouldn't it just stay like that or would it turn to u^3-6=0

Answer 12

I can see 10 u on the LHS and 9u on the RHS
