Solution for (4x^2-1x-3)/(4x^2-9x-9) equation:


D( x )

4*x^2-(9*x)-9 = 0

4*x^2-(9*x)-9 = 0

4*x^2-(9*x)-9 = 0

4*x^2-9*x-9 = 0

4*x^2-9*x-9 = 0

DELTA = (-9)^2-(-9*4*4)

DELTA = 225

DELTA > 0

x = (225^(1/2)+9)/(2*4) or x = (9-225^(1/2))/(2*4)

x = 3 or x = -3/4

x in (-oo:-3/4) U (-3/4:3) U (3:+oo)

(4*x^2-(1*x)-3)/(4*x^2-(9*x)-9) = 0

(4*x^2-x-3)/(4*x^2-9*x-9) = 0

4*x^2-x-3 = 0

4*x^2-x-3 = 0

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

DELTA = 49

DELTA > 0

x = (49^(1/2)+1)/(2*4) or x = (1-49^(1/2))/(2*4)

x = 1 or x = -3/4

(x+3/4)*(x-1) = 0

4*x^2-9*x-9 = 0

4*x^2-9*x-9 = 0

DELTA = (-9)^2-(-9*4*4)

DELTA = 225

DELTA > 0

x = (225^(1/2)+9)/(2*4) or x = (9-225^(1/2))/(2*4)

x = 3 or x = -3/4

(x+3/4)*(x-3) = 0

((x+3/4)*(x-1))/((x+3/4)*(x-3)) = 0

( x+3/4 )

x+3/4 = 0 // - 3/4

x = -3/4

( x-1 )

x-1 = 0 // + 1

x = 1

x in { -3/4}

x = 1
