[SQRT(x + 3)] - [SQRT(x - 2)] =1

I know I am supposed to square each side however my teacher tells me I ahve to foil the lefthand side of the equation. Cna someone please help me with this.

Thank you.

**bobpursley**, Tuesday, January 27, 2009 at 8:12pmwell, if you square both sides

you get (FOIL)

x+3-2sqrt(x-2)sqrt(x+3) + x-2=1

2x+2- 2sqrt( x^2+x-6)=1

or 2x+2-2=2sqrt(x^2+x-6)

square both sides

4x^2=4(x^2+x-6)

x=6

[SQRT(x + 7)] - 2[SQRT(x)] =-2

Beacause I see what you have showed me BUt i am stll a little bit confused. Please if you have the time help me. Thank you.
