Question

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

Answer 1

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?

Answer 2

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

Answer 3

I know, there's still a solution.

Answer 4

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

Answer 5

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

Answer 6

ok then thank u ;P

Answer 7

Answer 8

it was wrong lol but thanks

Answer 9
