Question

Solve the equation. Check both solutions and only write the real solution(s).
√2x+√3=x?

anonymous · Answer

Okay, square both sides.
x^2 = 3 + 2x
x^2 -2x-3 = 0
(x-3)(x+1) =0
So x = {3,-1}

Now check.

√2(3)+√3=3
√6+√3=3
Nope, so it's not 3.

√2(-1)+√3=-1
√-2+√3=-1
√-2 is IMPOSSIBRU

So no solutions?

??? !! that's what i got to but on my paper there's like different choices

anonymous · Answer

I know, there's still a solution.

anonymous · Answer

A:(-1)
B:(3)
C:(-1,3) those are my choices ...

anonymous · Answer

Hm, maybe they don't want you to check? Then mark {3,-1}. That's what I got at first.
