This is actually pretty urgent but for some reason I cant get into urgent Hw section. Been working on this for hours. And its for tomorrow.(Headbang)
Ok question goes...
Log (base3) (2-3x) = log (base9) (6x² -19x +2)
the answer is apparently -2 and -1/3. I can get -1/3 from solving a quadratic equation at the, but annoyinglyI get +2 as the other answer.
So far I have :
(lg (2-3x))/lg3 = (lg(6x² -19x +2))/lg 9
(lg 9) (lg [2-3x]) = (lg 3) (log [6x² -19x +2])
Im guessing this is where i go wrong because this is where the actual answers stop making sense
9 (lg [2-3x]) = 3(lg [6x² -19x +2])
9(2-3x) = 3 (6x² -19x +2)
18-27x = 18x² - 57x +6
0 = 18x² - 30x -12
0 = (18x +6)(x-2)
2 cannot be the answer beccause that would mean a negative log.
Pleaseeee Help, it may easily be something silly because im very tired. :(
