Solution for 4(7x-7)+12/x=13-4+3 equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

4*(7*x-7)+12/x = 3-4+13 // - 3-4+13

4*(7*x-7)+12/x-13-3+4 = 0

(4*x*(7*x-7))/x+12/x+(-13*x)/x+(-3*x)/x+(4*x)/x = 0

4*x*(7*x-7)-13*x-3*x+4*x+12 = 0

28*x^2-28*x-13*x-3*x+4*x+12 = 0

28*x^2-41*x-3*x+4*x+12 = 0

28*x^2-44*x+4*x+12 = 0

28*x^2-40*x+12 = 0

28*x^2-40*x+12 = 0

4*(7*x^2-10*x+3) = 0

7*x^2-10*x+3 = 0

DELTA = (-10)^2-(3*4*7)

DELTA = 16

DELTA > 0

x = (16^(1/2)+10)/(2*7) or x = (10-16^(1/2))/(2*7)

x = 1 or x = 3/7

4*(x-3/7)*(x-1) = 0

(4*(x-3/7)*(x-1))/x = 0

(4*(x-3/7)*(x-1))/x = 0 // * x

4*(x-3/7)*(x-1) = 0

( x-1 )

x-1 = 0 // + 1

x = 1

( x-3/7 )

x-3/7 = 0 // + 3/7

x = 3/7

x in { 1, 3/7 }
