Solution for 70=120/(x+1)^2 equation:


D( x )

(x+1)^2 = 0

(x+1)^2 = 0

(x+1)^2 = 0

x+1 = 0 // - 1

x in (-oo:-1) U (-1:+oo)

70 = 120/((x+1)^2) // - 120/((x+1)^2)

70-(120/((x+1)^2)) = 0

70-120*(x+1)^-2 = 0

70-120/((x+1)^2) = 0

(70*(x+1)^2)/((x+1)^2)-120/((x+1)^2) = 0

70*(x+1)^2-120 = 0

70*x^2+140*x-50 = 0

70*x^2+140*x-50 = 0

10*(7*x^2+14*x-5) = 0

7*x^2+14*x-5 = 0

DELTA = 14^2-(-5*4*7)

DELTA = 336

DELTA > 0

x = (336^(1/2)-14)/(2*7) or x = (-336^(1/2)-14)/(2*7)

x = (4*21^(1/2)-14)/14 or x = (-4*21^(1/2)-14)/14

10*(x-((-4*21^(1/2)-14)/14))*(x-((4*21^(1/2)-14)/14)) = 0

(10*(x-((-4*21^(1/2)-14)/14))*(x-((4*21^(1/2)-14)/14)))/((x+1)^2) = 0

(10*(x-((-4*21^(1/2)-14)/14))*(x-((4*21^(1/2)-14)/14)))/((x+1)^2) = 0 // * (x+1)^2

10*(x-((-4*21^(1/2)-14)/14))*(x-((4*21^(1/2)-14)/14)) = 0

( x-((-4*21^(1/2)-14)/14) )

x-((-4*21^(1/2)-14)/14) = 0 // + (-4*21^(1/2)-14)/14

x = (-4*21^(1/2)-14)/14

( x-((4*21^(1/2)-14)/14) )

x-((4*21^(1/2)-14)/14) = 0 // + (4*21^(1/2)-14)/14

x = (4*21^(1/2)-14)/14

x in { (-4*21^(1/2)-14)/14, (4*21^(1/2)-14)/14 }
