Forum Thread: Does Anyone Know A-Level Mechanics??

Please help because it has taken me a long time to get nearly nowhere.
:(

Express the following term in the form of kx^n

3x^2-18x
/
x^4

(In word form. Three x squared minus 18x divided by x to the power 4)

Thanks if you reply!

You might try plugging it into wolfram alpha, though you may need to add some parenthesis around the 3x^2-18x part, if all of that is supposed to be divided by x^4.

I have done what I thought was the correct answer and method and got the answer, 3x^-2 - 18x^-3. My answer is correct but my method is wrong. Thanks for the help. Much appreciated. :)

So... what was the answer?!?

3x^3(x-6)
