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

I dont understand how you did that..
anonymous
  • anonymous
which part
anonymous

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

but that's creatives tho

Ohh.. so i have to square one radical, and then the other?
anonymous
  • anonymous
So im squaring it a total of 2 times?
anonymous
  • anonymous
no, u put both radicals on one side, and 2 on the other side, which gives sqr(x+5)-sqrt(x-1)=2
anonymous
  • anonymous
then you square both sides of the equation
