X squared plus y squared
The sum of two squares cannot be factored.
Detailed description. We will discuss this further in the section Domains and ranges. There are many naturally occurring formulas whose graphs are not the graphs of functions. For example:. The first graph is a circle, the second is an ellipse, the third is two straight lines, and the fourth is a hyperbola. So these are not graphs of functions. It turns out that the most useful concept to help describe and understand this issue is very general.

X squared plus y squared
While it looks like you can just cancel out the squares with the square root, this only works if you have one square within the radical. Since we're adding two together, it's slightly different. The way that this expression CAN be simplified is by using polar coordinates, which are found in pre-calculus and above. Therefore, if we assume that the x and y this problem is using are the horizontal and vertical directions on a coordinate plane, we could technically rewrite our expression as:. Remember, this is probably NOT what your teacher is looking for, unless you're in pre-calculus or above. I would just stick with the original answer that the expression cannot be simplified. John D.
