Question

Simplify 1+4/x / 1-16 x^2

Answer 1

Answer:
`\frac{x+{4} }{x - 16x^(3) }`

Steps:

• 
  `(1+(4)/(x) )/(1-16x^(2) )`

• 
  `((x)/(x) +(4)/(x) )/((1-4x)(1+4x) )` (get common denominator (x) for top and factor bottom)

• 
  `\frac{x+{4} }{x(1-4x)(1+4x) }` (add numberator, then move x to denominator)

• 
  `\frac{x+{4} }{(x-4x^(2) )(1+4x) }` (multiply x and (1-4x) )

• 
  `\frac{x+{4} }{x+4x^(2) - 4x^(2) - 16x^(3) }` (FOIL denominator)

• 
  `\frac{x+{4} }{x - 16x^(3) }` (simplify)

Sorry about the delay. Hope this helps!

Answer 2

1+4/x x + 4

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

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

hope this helps, it probs won't but-
