Thread: Don't understand the question?

If [14x / root(2x+2)], what is one possible value of x?

14x / root(2x+2) is a term not an equation!

I don't know how to figure it out..

The answer to this was 1/2

There is something missing from the question.

Have you posted the whole question?

IF x = 1/2, then your expression must equal 7 / sqrt(3):
14x / sqrt(2x + 2) = 7 / sqrt(3)

possible domain question?

x can be any value such that 2x+2 > 0

Well, one possible value is x= 0! A more interesting question is "what are all the possible values of x.

14x / root(2x+2) is a term not an equation!

That's true, but irrelevant. This problem did say anything about "solving an equation".

No, an answer was 1/2. If x= 1/2 then which is a perfectly good result. x can be 1/2. If x= 0, as I gave before, then
which is also a valid answer. Or x= 1000000 (for no paticular reason) then which is again a perfectly good result. There are, literally, an infinite number of possible answers to this problem.

(But not all numbers. For example, if x= -1, that denominator becomes and you cannot divide by 0. If x= -2, you have , not a real number.)
