Solution for (35x^2+30x-11)/5x equation: 


x in (-oo:+oo)

x*((35*x^2+30*x-11)/5) = 0

(x*(35*x^2+30*x-11))/5 = 0

35*x^2+30*x-11 = 0

35*x^2+30*x-11 = 0

DELTA = 30^2-(-11*4*35)

DELTA = 2440

DELTA > 0

x = (2440^(1/2)-30)/(2*35) or x = (-2440^(1/2)-30)/(2*35)

x = (2*610^(1/2)-30)/70 or x = (-2*610^(1/2)-30)/70

(x-((-2*610^(1/2)-30)/70))*(x-((2*610^(1/2)-30)/70)) = 0

(x*(x-((-2*610^(1/2)-30)/70))*(x-((2*610^(1/2)-30)/70)))/5 = 0

( x-((-2*610^(1/2)-30)/70) )

x-((-2*610^(1/2)-30)/70) = 0 // + (-2*610^(1/2)-30)/70

x = (-2*610^(1/2)-30)/70

( x-((2*610^(1/2)-30)/70) )

x-((2*610^(1/2)-30)/70) = 0 // + (2*610^(1/2)-30)/70

x = (2*610^(1/2)-30)/70

( x )

x = 0

x in { (-2*610^(1/2)-30)/70, (2*610^(1/2)-30)/70, 0 }
