Apologies if I have posted this in the wrong place.
Please could someone help me with this?
Is it possible to rearrange the following equation so that it is expressed in terms of x? Have been trying for ages without luck.
x^2 = b^2 + (c - (ac/(a+x)))^2
Any help would be much appreciated.
A good place to start would be to use foil to expand that squared term
You should then be able to multiply through by to clear the fraction
You will eventually have to expand it and it won't be pretty but it should be simple enough using FOIL and the distributive property
and you get a rather nasty quartic equation which nevertheless can be solved with the help
of Ferrari-Cardano formulae (pretty frightening creatures!), or perhaps you know some relation
between the coefficients which could simplify the above (for example, could make things waaaaaay simpler)
Collect those with an x term on the right hand side.
This is equal to the LHS
Collect like terms
Which is a nasty quartic equation but will probably be easier if you use an iterative method
