You can also multiply both sides by 12 to get
Doing past papers at the mo & have a quadratic which I am stuck on
find fixed points of f(x) = x^2+(13/12)x-1/2
Now, fixed points are when f(x) = x, so I have subtracted x from both sides
=> x^2 + (1/12)x - 1/2 = 0 to make an easier(?) quadratic
so a=1, b=1/12 & c=-1/2
Sub into formula & I am now stuck as the sqrt comes up as negative & I'm not sure enough about completing the square.
I also have similar equation f(x) = x^2 + (14/15)x - 2/5. Stuck here, too
Would appreciate a little help.
I have the second example, too, which I have still not been able to do. Similar equation f(x) = x^2 + (14/15)x - 2/5
Please could someone point me in the right direction with this, too. It is part of a fixed point iteration question.
I'm having trouble with that, too, but I must keep trying.
