Basically, the question is (x^2 / x - 1) / (3x^2 / x + 4).

simplify parentheses first.  x^2 divided by x = x thus...

(x / -1) / (3x / 4)

now the x cancels out...

(-1) / (3/4)

= (-1) / (0.75)

= -1.334

I am pretty sure this is how to do it, but I think it would be wise to double check with someone.
