Solve
2+ the square root of 4-x=x

what is your question?


ok lets start by arranging everything so its easier to solve..
u want to put the square root(4-x)on one side of the equation and the 2 on the other side...

square root(4-x) = x - 2;

now..to get rid of the square root..u have to square both sides..i.e both sides have to be raised by the power of 2

4-x = (x - 2)^2

use the formula (a-b)^2 = a^2 -2ab+ b^2
and solve...
see if u can get this far..and actually continue to solve it
good luk!
