Question 152752: Solve for all values of x: square root sign (x+7) - square root sign (x+2)=1
I am not sure what to do with this question. I think maybe I should mutilply by x+7 and x+5 to remove the square root sign, but then I am lost
Thanks

Solve for all values of x: square root sign (x+7) - square root sign (x+2)=1
;
= 1
:
+ 1; add to both sides
:
x + 7 = (x+2) + + 1; Square both sides, (FOIL the right side)
:
x + 7 = x + 3 +
:
x - x + 7 - 3 =
:
4 =
:
16 = 4(x+2); squared both sides, gets rid of the 2nd radical
:
16 = 4x + 8
:
16 - 8 = 4x
x =
x = 2
:
:
Check solution in original equation:
= 1
= 1; confirms our solution
