We are given the following
(i)
step 1 - move the x^(1/2) terms to the right side as
(ii)
step 2 - square both sides to get
(iii)
step 3 - subtract 4x to get
(iv)
step 4 - factor to get
(v)
step 5 - solve for x to get
x= 9
or
x = 25
If we check x = 9, we find it doesn't work, so our only answer is x = 25.
