Answer 1

no sorry! we don't study mathematics generally digitally ( computer or mobile ) , we use textbook, notebook and pain !

Answer 2

You can determine the root of the equation by multiple methods. However, that answer is correct. The root is -2.

Explanation:

A root is where the graph crosses the x-axis. One trick I use to see if it is a root is by taking the numerator and plugging in the number for x. For example,
`(x+2)/(x^(2) -2)`, and take the -2 and plug it in for x. The numerator would cancel out because -2 + 2 = 0. That is the way you can determine if it is a root or not.

I hope this helps, if you need any clarification let me know :)
