Trying to find the e-mail for WS magic co. in China

There is a methodical process to problem solving.The information that you have provided is inadequate to work with. You likely have additional data that would be helpful in searching down this company. The following are but a few questions that if answered would be helpful.
-What does the company produce,and what is the name and product # in question ?
-Do you have the packaging that the product came in, and if so what is the full name and address specified on it?
-The product will have a label on it specifying product, and manufacturer information. Have you checked the back or bottom of the item for this information?
-What company did you purchase the product from, and have you contacted them for manufacturer information, or the answer to your question ?

With your co operation, I have no doubt that we "the Fixya nation" will then be equiped with the essentials necessary to seeking out an answer on your behalf.

I was wondering how I would slove this problem. -x^2+1=4 I am really coufused on this one.

x^2 + 1 = 4
Subtract 1 from both sides: x^2 = 3
Take the square root of both sides: x = sqrt(3)

The answer is: x is equal to the square root of 3.
