Question 264215: x^1/2-3x^1/4+2=0
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! x^1/2-3x^1/4+2=0
---
[x^(1/4)]^2 - 3x^(1/4) + 2 = 0
Let w = x^(1/4)
-----
w^2 - 3w + 2 = 0
Factor:
(w-2)(w-1) = 0
w = 2 or w = 1
----
Solve for "x":
x^(1/4) = 2 or x^(1/4) = 1
x = 16 or x = 1
