Kudos for the right answer and explanation
Take: \(y^2-11y+30=0\)
Factor the left side: \((y-5)(y-6)=0\)
So, EITHER \(y=5\) OR \(y=6\)
If \(y=5\), then Quantity B is greater
If \(y=6\), then Quantity B is greater
Since \(y=5\) and \(y=6\) are the only two possible values of y, the correct answer is B
