Solve and show work! :D Medal Received if correct! :D

\[s + 5 = \frac{ 6 }{ s }\]

zepdrix (zepdrix):

Hey Jay. So if we start by multiplying both sides by \(\large s\), we get something like this,\[\large s(s+5)=\frac{6}{s}s\]Do you understand why we would want to do that? What happens on the right side?

OpenStudy (firejay5):

cancels out @zepdrix

zepdrix (zepdrix):

Ok good.\[\large s(s+5)=6\]Next distribute the \(s\) to each term in the brackets.

OpenStudy (firejay5):

okay what now @zepdrix So far: \[s^2 + 5s = 6\]

zepdrix (zepdrix):

Subtract 6 from each side, and we're left with a nice quadratic.\[\large s^2+5s-6=0\]

zepdrix (zepdrix):

Hmm I think this will factor very nicely. Are you comfortable with factoring?

OpenStudy (firejay5):

I figured this out already and both are solutions to the problem. :D @zepdrix

zepdrix (zepdrix):

Yay good job. :)

OpenStudy (firejay5):

x = -6 & x = 1

zepdrix (zepdrix):

Ah yes :O good good.

OpenStudy (firejay5):

are those the correct answer

zepdrix (zepdrix):

\[\large (s+6)(s-1)=0\] Giving us,\[\large s=-6 \qquad \qquad s=1\] Yup looks good.

OpenStudy (firejay5):

awesome
