Solution for x+2/(5x-15)*(10x^2-25x-15) equation:


D( x )

5*x-15 = 0

5*x-15 = 0

5*x-15 = 0

5*x-15 = 0 // + 15

5*x = 15 // : 5

x = 15/5

x = 3

x in (-oo:3) U (3:+oo)

(2/(5*x-15))*(10*x^2-(25*x)-15)+x = 0

(2/(5*x-15))*(10*x^2-25*x-15)+x = 0

(2*(10*x^2-25*x-15))/(5*x-15)+x = 0

(2*(10*x^2-25*x-15))/(5*x-15)+(x*(5*x-15))/(5*x-15) = 0

2*(10*x^2-25*x-15)+x*(5*x-15) = 0

25*x^2-65*x-30 = 0

25*x^2-65*x-30 = 0

5*(5*x^2-13*x-6) = 0

5*x^2-13*x-6 = 0

DELTA = (-13)^2-(-6*4*5)

DELTA = 289

DELTA > 0

x = (289^(1/2)+13)/(2*5) or x = (13-289^(1/2))/(2*5)

x = 3 or x = -2/5

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

(5*(x+2/5)*(x-3))/(5*x-15) = 0

(5*(x+2/5)*(x-3))/(5*x-15) = 0 // * 5*x-15

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

( x+2/5 )

x+2/5 = 0 // - 2/5

x = -2/5

( x-3 )

x-3 = 0 // + 3

x = 3

x in { 3}

x = -2/5
