Someone told me the title line is wrong for the abuse of the verb confirm. I was told I could say either of the following:

I want to confirm this is true.

I want to confirm this is not ture.

But not the combination of them as titled.

What's your opinions, native English speakers? Thanks a lot.

I have no problem with it. It states that confirmation is required as to whether something is or is not true.

I'd say:
I want to find whether or not this is true.
because this is truly a process of finding/discovery, not of confimation.

7 on "find whether or not this is true"
but you will find:
12 on "confirm whether or not this is true"

OseeWhat's your opinions, native English speakers?
I agree it's not exactly right, but it's understandable as is anyway. One believes that X, but one isn't quite sure, so one tries to confirm that X. Confirming whether X is like believing whether X, and we don't say, "I believe whether ...".
Not a serious mistake, though, unless you're being picky. I'm pretty flexible on this one.

But how about in such a context: I was told how to solve a problem in school. After going back to home, I wrote down the solution by myself. Then next morning, I gave my solution to the teacher to check. So I did need his or her confirmation on whether or not my solution was true or right. Using find in such a situation is kind of not so good as using confirm. Do you think so? Thanks.

I agree with you - you are asking for confirmation of something. That is different from wanting to find out if something is true or not.

YES
