Answer:
The simplest form is 2(3x - 7)/x(x³ + 4)
Step-by-step explanation:
* Lets revise how can divide fraction by fraction
- To simplify (a/b)/(c/d), change it to (a/b) ÷ (c/d)
∵ a/b ÷ c/d
- To solve it change the division sign to multiplication sign and
reciprocal the fraction after the sign
∴ a/b × d/c = ad/bc
* Now lets solve the problem
∵
- Lets take the denominator and simplify by make it a single
fraction, let the denominator of it 2x and change
the numerator
∴
∴ The fraction =
* Now lets change it by (up ÷ down)
∴ ÷
- Change the division sign to multiplication sign and reciprocal
the fraction after the sign
∴ ×
∴
- We can simplify x up with x down
∴
* The simplest form is 2(3x - 7)/x(x³ + 4)
