s+7/s=-8

OpenStudy (anonymous):

you dont know how to solve proportions pupo

OpenStudy (anonymous):

I would simplify the problem to get rid of the fraction.

OpenStudy (anonymous):

of course you simplify the problem, do you want to complicate the problem

OpenStudy (turingtest):

Lagrange is mad today...

OpenStudy (turingtest):

should there be any parentheses in the problem? is it s+(7/s)=-8 or (s+7)/s=-8

OpenStudy (radar):

Is that (s+7)/s or never mind turing Test Is getting it straightened out

OpenStudy (radar):

Try it both ways: (s+7)/s=-8 then -8s=s+7 9s=-7 s=-7/9

OpenStudy (turingtest):

How generous of you radar, to do the problem twice. A medal for you!

OpenStudy (radar):

or if it is s + (7/s) =-8 TuringTest, I'm retired...I have the time lol Multiplying all terms by s gives \[s ^{2}+7=-8s\] \[s ^{2}+8s+7=0\]

OpenStudy (radar):

s=-1 s=-7 As it nicely factors (s+1)(s+7)

OpenStudy (turingtest):

thanks
