Answer 1

- Add a using System.Xml directive up at the top of your code behind file.
- Load the XML data into an XmlDocument object
- Use SelectSingleNode to grab the node in question, and assign it to an XmlNode object
- Assign the form value to the InnerText property of the XmlNode.
- Save the XmlDocument object (using the Save method) out to the location you want the file saved to (overwrite the old, or whatever.)

Answer 2

0.5 the coefficient of x (2) to get a million. Now write +a million - a million interior the expression. on account that +a million-a million is 0, you haven't any longer extra something to the equation. you have basically completed the squares to assist you to factorize x^2 + 2x + a million - a million - 24 (x + a million)^2 - 25 (x + a million)^2 - 5^2 a = x, b = a million and c = 5
