Solution for (-5)/(2w-10)+2=(1)/(w+5) equation:


D( w )

w+5 = 0

2*w-10 = 0

w+5 = 0

w+5 = 0

w+5 = 0 // - 5

w = -5

2*w-10 = 0

2*w-10 = 0

2*w-10 = 0 // + 10

2*w = 10 // : 2

w = 10/2

w = 5

w in (-oo:-5) U (-5:5) U (5:+oo)

2-5/(2*w-10) = 1/(w+5) // - 1/(w+5)

2-5/(2*w-10)-(1/(w+5)) = 0

2-5/(2*w-10)-(w+5)^-1 = 0

2-5/(2*w-10)-1/(w+5) = 0

(-5*(w+5))/((2*w-10)*(w+5))+(-1*(2*w-10))/((2*w-10)*(w+5))+(2*(2*w-10)*(w+5))/((2*w-10)*(w+5)) = 0

2*(2*w-10)*(w+5)-5*(w+5)-1*(2*w-10) = 0

4*w^2-7*w-100-15 = 0

4*w^2-7*w-115 = 0

4*w^2-7*w-115 = 0

4*w^2-7*w-115 = 0

DELTA = (-7)^2-(-115*4*4)

DELTA = 1889

DELTA > 0

w = (1889^(1/2)+7)/(2*4) or w = (7-1889^(1/2))/(2*4)

w = (1889^(1/2)+7)/8 or w = (7-1889^(1/2))/8

(w-((7-1889^(1/2))/8))*(w-((1889^(1/2)+7)/8)) = 0

((w-((7-1889^(1/2))/8))*(w-((1889^(1/2)+7)/8)))/((2*w-10)*(w+5)) = 0

((w-((7-1889^(1/2))/8))*(w-((1889^(1/2)+7)/8)))/((2*w-10)*(w+5)) = 0 // * (2*w-10)*(w+5)

(w-((7-1889^(1/2))/8))*(w-((1889^(1/2)+7)/8)) = 0

( w-((1889^(1/2)+7)/8) )

w-((1889^(1/2)+7)/8) = 0 // + (1889^(1/2)+7)/8

w = (1889^(1/2)+7)/8

( w-((7-1889^(1/2))/8) )

w-((7-1889^(1/2))/8) = 0 // + (7-1889^(1/2))/8

w = (7-1889^(1/2))/8

w in { (1889^(1/2)+7)/8, (7-1889^(1/2))/8 }
