1+4/x                       x + 4

------------   =            -------------  

1-16 x^2           x(-4x + 1) (4x + 1)

hope this helps, it probs won't but-

Answer: [tex]\frac{x+{4} }{x - 16x^{3} }[/tex]

Steps:

  • [tex]\frac{1+\frac{4}{x} }{1-16x^{2} }[/tex]
  • [tex]\frac{\frac{x}{x} +\frac{4}{x} }{(1-4x)(1+4x) }[/tex] (get common denominator (x) for top and factor bottom)
  • [tex]\frac{x+{4} }{x(1-4x)(1+4x) }[/tex] (add numberator, then move x to denominator)
  • [tex]\frac{x+{4} }{(x-4x^{2} )(1+4x) }[/tex] (multiply x and (1-4x) )
  • [tex]\frac{x+{4} }{x+4x^{2} - 4x^{2} - 16x^{3} }[/tex] (FOIL denominator)
  • [tex]\frac{x+{4} }{x - 16x^{3} }[/tex] (simplify)

Sorry about the delay. Hope this helps!
