Solution for (3x^2-7x+2)/(3x^2+2x-1) equation:


D( x )

3*x^2+2*x-1 = 0

3*x^2+2*x-1 = 0

3*x^2+2*x-1 = 0

3*x^2+2*x-1 = 0

DELTA = 2^2-(-1*3*4)

DELTA = 16

DELTA > 0

x = (16^(1/2)-2)/(2*3) or x = (-16^(1/2)-2)/(2*3)

x = 1/3 or x = -1

x in (-oo:-1) U (-1:1/3) U (1/3:+oo)

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

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

3*x^2-7*x+2 = 0

3*x^2-7*x+2 = 0

DELTA = (-7)^2-(2*3*4)

DELTA = 25

DELTA > 0

x = (25^(1/2)+7)/(2*3) or x = (7-25^(1/2))/(2*3)

x = 2 or x = 1/3

(x-1/3)*(x-2) = 0

3*x^2+2*x-1 = 0

3*x^2+2*x-1 = 0

DELTA = 2^2-(-1*3*4)

DELTA = 16

DELTA > 0

x = (16^(1/2)-2)/(2*3) or x = (-16^(1/2)-2)/(2*3)

x = 1/3 or x = -1

(x+1)*(x-1/3) = 0

((x-1/3)*(x-2))/((x+1)*(x-1/3)) = 0

( x-1/3 )

x-1/3 = 0 // + 1/3

x = 1/3

( x-2 )

x-2 = 0 // + 2

x = 2

x in { 1/3}

x = 2
