Why say fifteen points when it's only 5; people can see how much it's worth before even doing it.
Anyways, is there a plus in between the 2f 3 and between the -14 3?
If so, then w and k equal all real numbers and
[tex]f = \frac{ - 1005}{22} + \frac{12}{11}k + \frac{1}{11} {w}^{2} k - \frac{ 81}{22} {w}^{2} [/tex]
However if not, then I suggest downloading photo math and inserting it in the calculator itself to be exact.
