Question 309741: I need help with how to solve this problem. Thanks!
1/x - 2/1 - x = 1/2
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
1/x - 2/1 - x = 1/2
1/x-x=1/2+2
(1-x*x)/x=2.5
(1-x^2)/x=2.5
2.5x=1-x^2
x^2+2.5x-1=0

x=(-2.5+-sqrt[2.5^2-4*1*-1])/2*1
x=(2.5+-sqrt[6.25+4])/2
x=(-2.5+-sqrt10.25)/2
x=(-2.5+-3.2)/2
x=-2.5+3.2)/2
x=.7/2
x=.35 ans.
(-2.5-3.2)/2
x=-5.7/2
x=2.85 ans.
