Select ALL of the following for which there exist nonzero constants which can be substituted into the equation to make it true.

Aa/(x-2)(x+7)=b/(x-2)

Ba/(x-2)(x+7)=b/(x-2)+c/(x+7)

Ca/(x-2)(x+7)=b/(x-2)+c/(x+7)+6

Dnone of the above?

The non zero constant is where if the both variables are substituted as zero the resulting would e non zero but also it should be valid and would make the equation true in the process of equality. I think the best answer to this question is D. none of the above
