Fact
''prove that someone or something is false.''
If a hypothesis does not generate any observational tests, there is nothing that a scientist can do with itRead more: Explain_why_a_hypothesis_must_be_testableANS2:If an hypothesis is not testable, it cannot be provable false. If it cannot be provable false it cannot be supported. If it cannot be supported, it adds nothing to science. An hypothesis is a "no-win" proposition. You need to try to prove it false. That being the case, you either prove it false (lose) or you fail to prove it false (lose). Failing to prove an hypothesis false is the basis for supporting it.
It is rare and difficult to prove a hypothesis true or false through experimentation. While it is typically easy to prove something completely false, proving it true is another story.
The opposite of "prove" with a prefix is "disprove." It means to show that something is false or incorrect through evidence or reasoning.
"Refute" means to prove something to be wrong or false by providing evidence or arguments to the contrary.
A logical sequence in an argument is a way to prove a step has a logical consequence. Every proposition in an argument must be tested in this fashion to prove that every action has a reaction.
If x is a null matrix then Ax = Bx for any matrices A and B including when A not equal to B. So the proposition in the question is false and therefore cannot be proven.
Prove that if it were true then there must be a contradiction.
If you mean how can you prove that the drug test results were false, ask for a retest.
An idea that explains something could be called a theory. Good scientific theories are falsifiable which means you could prove it to be false. You can never prove a theory to be true, you can only provide evidence that supports the theory.
