2000/((x+1)^1)+4000/((x+1)^2)-4000 = 0

2000/(x+1)+4000/((x+1)^2)-4000 = 0

(2000*(x+1))/((x+1)^2)+4000/((x+1)^2)+(-4000*(x+1)^2)/((x+1)^2) = 0

2000*(x+1)-4000*(x+1)^2+4000 = 0

2000*x-4000*x^2-8000*x-4000+6000 = 0

2000-4000*x^2-6000*x = 0

2000-4000*x^2-6000*x = 0

2000*(1-2*x^2-3*x) = 0

1-2*x^2-3*x = 0

DELTA = (-3)^2-(-2*1*4)

DELTA = 17

DELTA > 0

x = (17^(1/2)+3)/(-2*2) or x = (3-17^(1/2))/(-2*2)

x = (17^(1/2)+3)/(-4) or x = (3-17^(1/2))/(-4)

2000*(x-((17^(1/2)+3)/(-4)))*(x-((3-17^(1/2))/(-4))) = 0

(2000*(x-((17^(1/2)+3)/(-4)))*(x-((3-17^(1/2))/(-4))))/((x+1)^2) = 0

(2000*(x-((17^(1/2)+3)/(-4)))*(x-((3-17^(1/2))/(-4))))/((x+1)^2) = 0 // * (x+1)^2

2000*(x-((17^(1/2)+3)/(-4)))*(x-((3-17^(1/2))/(-4))) = 0

( x-((17^(1/2)+3)/(-4)) )

x-((17^(1/2)+3)/(-4)) = 0 // + (17^(1/2)+3)/(-4)

x = (17^(1/2)+3)/(-4)

( x-((3-17^(1/2))/(-4)) )

x-((3-17^(1/2))/(-4)) = 0 // + (3-17^(1/2))/(-4)

x = (3-17^(1/2))/(-4)

x in { (17^(1/2)+3)/(-4), (3-17^(1/2))/(-4) }
