rishavraj (rishavraj):

its \[\frac{ x - 2 }{ x + 2 } = \frac{ 3 }{ x }\] cross multiply

OpenStudy (anonymous):

x2-2x/3x+6

rishavraj (rishavraj):

x^2 - 2x = 3x + 6

OpenStudy (anonymous):

x2=x+6

rishavraj (rishavraj):

hmmm nah..... x^2 - 5x - 6 = 0 solve the equation

OpenStudy (anonymous):

Ok, hold on..

OpenStudy (anonymous):

(x-6)(x+1)

rishavraj (rishavraj):

so x = 6 and -1 whichever of the two doesnot satisfy the equation is an extraneous solution

OpenStudy (anonymous):

the -1 doesnt

OpenStudy (anonymous):

bc the 6 makes each side 1/2
