Question 29666
This is a complex fraction but the way you have written it, there is some missing information.   Which one of these best repersents the problem??

{{{(x^3 +x^2) / (((x^2 - 16x +4) / (3x^4 + x^3 - 2x^2))) }}} 

or like ....

{{{(((x^3 +x^2) / (x^2 - 16x +4))) / (3x^4 + x^3 - 2x^2) }}} 

It makes a difference when solving this.
