Solution for (x^2+4x-12)/(x^2-5x+6) equation:


D( x )

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

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

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

x^2-5*x+6 = 0

x^2-5*x+6 = 0

DELTA = (-5)^2-(1*4*6)

DELTA = 1

DELTA > 0

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

x = 3 or x = 2

x in (-oo:2) U (2:3) U (3:+oo)

(x^2+4*x-12)/(x^2-(5*x)+6) = 0

(x^2+4*x-12)/(x^2-5*x+6) = 0

x^2+4*x-12 = 0

x^2+4*x-12 = 0

DELTA = 4^2-(-12*1*4)

DELTA = 64

DELTA > 0

x = (64^(1/2)-4)/(1*2) or x = (-64^(1/2)-4)/(1*2)

x = 2 or x = -6

(x+6)*(x-2) = 0

x^2-5*x+6 = 0

x^2-5*x+6 = 0

DELTA = (-5)^2-(1*4*6)

DELTA = 1

DELTA > 0

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

x = 3 or x = 2

(x-2)*(x-3) = 0

((x+6)*(x-2))/((x-2)*(x-3)) = 0

( x+6 )

x+6 = 0 // - 6

x = -6

( x-2 )

x-2 = 0 // + 2

x = 2

x in { 2}

x = -6
