I have no clue if this is correct. If it isn't, could somebody point me where I went wrong?
+129852 simplify z-8/z -5z-38/11z
I'm going to assume that you either mean this: z-8/z -5z-(38/11)z
or this: z- 8/z -5z-38/(11z)
If it's the first, we have [z - 5z - (38/11)z)] - 8/z = (-82/11)z - 8/z =
-[(82z^2 + 88] / (11z)]
If it's the second, we have (z - 5z) - [(38/(11z) + 8/z)] = (-4z) -[(38/(11z) + (88/(11z)] = -[44z^2 + (126)] / (11z)]
+118677 Please GoldenLeaf, only answer questions if you think you are certain of the method.
Otherwise just wait till someone more knowledgable does it and learn from them!
Okay GoldenLeaf - this is one place that you went wrong. I have not checked your whole answer.
$$1z - 8/z - 5z - 38/11 * 1z$$
$$z(1z - 8/z - 5z - 38/11 * 1z)$$
The second one does not follow from the first!
$$z(1z-\frac{8}{z}-5z - \frac{38}{11} * 1z)
=z^2-8-5z^2- \frac{38z^2}{11}$$
+1006 Alas! I have failed a math once again =(
Math has not been flowing through me recently it seems.
