# Why is this a duplicate?

Recently I asked this question: https://codegolf.stackexchange.com/questions/75040/solve-a-quadratic-expression. Seconds after I posted, it was flagged as a duplicate of Resolve quadratic equation, and was downvoted several times. The two titles look similar, but, as I put in the comments,

...The main challenge for mine is interpreting a string, whereas the other question's main challenge is solving a quadratic (as it takes three numbers separated by commas such as 1,2,3 rather than a visual expression such as x^2+2x+3).

I'm not sure why people who actually read my question would not be able to see that my challenge is different.

Can someone explain why it's considered a duplicate?

• Perhaps because parsing an expression is not interesting nor significant enough for the challenges to differ. – Conor O'Brien Mar 8 '16 at 0:38
• We like 1-task challenges around here. If the "meat" of your challenge is parsing the expression, I'd recommend removing the "solve the equation" part, e.g: "5x+2x^2+4" -> (4,5,2). Otherwise, if the meat is the solving the equation part, then its a duplicate. – Nathan Merrill Mar 8 '16 at 0:58
