Question 17588: square root x-2-8=0 using graphing utlity to slove this problem I hope someone is here is that good to solve this thank you so much Answer by rapaljer(4671) (Show Source):
You can put this solution on YOUR website! Assuming that you mean , let's just graph it and see where it crosses the x axis. You can assume because of the square root that . That point is the value of x that is the solution for this equation:
The normal graph for x from -10 to 10 will NOT work here. You will also have to use a fairly large value of x, like maybe up to x=100 to be able to see where the graph crosses the x axis. It turns out that x= 66 is the value that works, so this is the solution. X=66, and it checks also!
