Question

Which expression is equivalent to the following complex fraction?ХX-3x2-9X-3X+ 31X+ 3ХOХX+3

Answer 1

To solve the given fraction, we have to multiply the extremes parts and the inner parts between each other.

$\frac{x(x^2-9)}{x^2(x-3)}$

Then, we factor the numerator

$\frac{x(x+3)(x-3)}{x^2(x-3)}$

At last, we simplify

$\frac{x+3}{x}$

Hence, the answer is the third option.
