    first put two radicals on one side, 2 on the other side

    square both sides, you'll get x+5-2sqrt(x^2+4x-5)+x-1=4 which simplifies as sqrt(x^2+4x-5)=x now square both side again, you get x^2+4x-5=x^2 which gives x=5/4

    for radical problems just keep squaring till all radical symbols disappear

    btw, you can't square the whole equation, math doesn't work that way

    Ohh.. so i have to square one radical, and then the other?

    So im squaring it a total of 2 times?

    no, u put both radicals on one side, and 2 on the other side, which gives sqr(x+5)-sqrt(x-1)=2

    then you square both sides of the equation
