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

You want to get the <span>denominator (bottom) of the fraction to a number such as 10, 100 or 1,000. Then you are able to change the fraction into a decimal by having the decimal point and the number afterwards, for example: 1/5=2/10, 2/10=.2.</span>
