Solution for 5/(5x-10)+(x-3)/(2-x) equation:


D( x )

2-x = 0

5*x-10 = 0

2-x = 0

2-x = 0

2-x = 0 // - 2

-x = -2 // * -1

x = 2

5*x-10 = 0

5*x-10 = 0

5*x-10 = 0 // + 10

5*x = 10 // : 5

x = 10/5

x = 2

x in (-oo:2) U (2:+oo)

5/(5*x-10)+(x-3)/(2-x) = 0

(5*(2-x))/((5*x-10)*(2-x))+((x-3)*(5*x-10))/((5*x-10)*(2-x)) = 0

5*(2-x)+(x-3)*(5*x-10) = 0

5*x^2-30*x+40 = 0

5*x^2-30*x+40 = 0

5*(x^2-6*x+8) = 0

x^2-6*x+8 = 0

DELTA = (-6)^2-(1*4*8)

DELTA = 4

DELTA > 0

x = (4^(1/2)+6)/(1*2) or x = (6-4^(1/2))/(1*2)

x = 4 or x = 2

5*(x-2)*(x-4) = 0

(5*(x-2)*(x-4))/((5*x-10)*(2-x)) = 0

(5*(x-2)*(x-4))/((5*x-10)*(2-x)) = 0 // * (5*x-10)*(2-x)

5*(x-2)*(x-4) = 0

( x-2 )

x-2 = 0 // + 2

x = 2

( x-4 )

x-4 = 0 // + 4

x = 4

x in { 2}

x = 4
