Is this the expression you're looking at? \[\frac{\frac{4x}{x^2  9}}{\frac{8x^2}{x^2 + 6x + 9}}\]

It's a bit ambiguous when written out horizontally like that. I recommend liberal use of parentheses.

Yes that is correct.

If you're going to enter it into a calculator (or wolframalpha), then you'll need to express it like this: (4x/(x^2  9)) / ((8x^2)/(x^2 + 6x + 9)) Even then, I tried that in wolframalpha, and it didn't give the fully simplified result.

\[1/2\,{\frac {x+3}{ \left( x3 \right) x}}\]

Best first step is to express the fractiondivision as fractionmulitplication. (Division is defined as multiplication by the reciprcal.) Then factor the crap out of everything and see what cancels.

from wolfram if you type it like this 4*x/((x^29)*(8*x^2/(x^2+6*x+9)))

Or you could just write it down and do the algebra . . .

Guys, both your formula's give the same results in WolfRam....

Yep, and neither shows Lindsey how to do it herself.

Intermediate step looks like this: \[\frac{4x}{(x+3)(x3)} \space \times \space \frac{(x+3)(x+3)}{8x^2}\]
