Question 156543: (square root of x + 2)- x = 0
(x+2)^2 -x = 0
(x+2)^1/2^2/1 - x + x = 0 + x^2/1
x + 2 - 2 = x^2/1 - 2
x = x^2/1^1/2 - 2
x - x = x - 2
0 + 2 = x - 2 + 2
2 = x

Question 156836: I need to resolve x, AB, BC and AC, where A, B and C are points on a line. A is leftmost, C is rightmost, and B is somewhere in between.
AB = 2x+1
BC = x-2
AC = sqrt (x^2 + 25x + 5)
Was able to write, 2x+1+x-2 = sqrt (x^2+25x+5), which reduces to 3x-1 = sqrt (x^2 + 25x + 5).
I don't know how to eliminate the square root, especially when there is an exponential along with it.
Please help.
Thank you.
