Question 581294: Please help he solve this equation
+sqrt%282x%2B5%29=X-5+
I have to be able to fill out the table for it looks like this
x y1 y2
0 sqrt%285%29 -5
3 -2
5 sqrt%2815%29
10
15
18
20 sqrt%2845%29
And then I have to give the solution for x
I have to draw the graph and then state what the solution point (x,y) is.
I have no idea what this means.
Thanks

You can put this solution on YOUR website!
+sqrt%282x%2B5%29=X-5+
Square both sides
2x%2B5+=+x%5E2+-+10x+%2B+25
x%5E2+-+12x+%2B+20+=+0
(x-2)*(x-10) = 0
x = 2, x = 10
