I see you have graph paper.
You must be plotting something

Re: x =
Hi;
x = 10, x = 8, x = -8, x = -10
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

help me on another one
\frac{c}{c-5}=\frac{4}{c-4}
FInd c.
Also, the LaTeX doesn't seem to work..

Re: x =
If you cross multiply,then you'd get c^2-4c=4c-20 which is c^2-8c+20=0,now you just have to find the polynomial's roots.

Re: x =
Hi;
I am getting
c = 4 - 2 i and c = 4 + 2 i
