did i do it right?

when trying to get x alone is b^2-c^2+2cx = a^2 --> a^2-b^2+c^2/2c = x ?


is (a^2-b^2+c^2/2c)^2 = -2a^2b^2+2a^2c^2-2b^2c^2+a^4+b^4+c^4 ?

Hi girlnamedfreak;

For the first one:

For the last one, I will have to go with what I think that gobblygook is.

Or maybe you want this?


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
