Solution for (3x^2-21x/5x^2)/(x^2-2x-35/10x) equation:


D( x )

x^2-(2*x)-((35/10)*x) = 0

x^2-(2*x)-((35/10)*x) = 0

x^2-(2*x)-((35/10)*x) = 0

x^2-2*x+(-7/2)*x = 0

x^2-11/2*x = 0

DELTA = (-11/2)^2-(0*1*4)

DELTA = 121/4

DELTA > 0

x = ((121/4)^(1/2)+11/2)/(1*2) or x = (11/2-(121/4)^(1/2))/(1*2)

x = 11/2 or x = 0

x in (-oo:0) U (0:11/2) U (11/2:+oo)

(3*x^2-(((21*x)/5)*x^2))/(x^2-(2*x)-((35/10)*x)) = 0

((-21/5)*x^3+3*x^2)/(x^2-2*x+(-7/2)*x) = 0

(3*x^2-21/5*x^3)/(x^2-11/2*x) = 0

3*x^2-21/5*x^3 = 0

3*x^2*(1-7/5*x) = 0

1-7/5*x = 0 // - 1

-7/5*x = -1 // : -7/5

x = -1/(-7/5)

x = 5/7

3*x^2*(x-5/7) = 0

x^2-11/2*x = 0

x*(x-11/2) = 0

x-11/2 = 0 // + 11/2

x = 11/2

x*(x-11/2) = 0

(3*x^2*(x-5/7))/(x*(x-11/2)) = 0

( 3*x^2 )

3*x^2 = 0 // : 3

x^2 = 0

x = 0

( x-5/7 )

x-5/7 = 0 // + 5/7

x = 5/7

x in { 0}

x = 5/7
