Question

State the restrictions on the variable and classify the restrictions as removable or nonremovable. 

(x−3)/(x+4)÷(x^2−1)/x
 

Question 1
What is being asked in the problem and what does that mean? What plan am I going to try? (1 sentence)

Question 2
I will write out my response to the question, explaining my answer and what it means. (1 sentence)

(solve step by step at the end)

Answer 1

you cannot eliminate the x factor. Where do you justify multiplying by x/x?
The final expression is
(x-3)/(x+4) * x / (x+1)(x-1) = x(x-3) / (x+4)(x^2-1)

everything else you said is ok.
x=0 still must be eliminated, since the original equation requires it.
