Re: help with equation
Hi planetdomi;
Take the square root of both sides.
Of course there is a negative answer too but I have left that one out.
Welcome to the forum.
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.
