Multiple Choice

A data analyst is peer-reviewing a colleague's work on the simplification of the expression:

y2y62y+24y6\frac{y^2}{y-6} - \frac{2y+24}{y-6}

The colleague combined the numerators and wrote the result as:

y22y+24y6\frac{y^2 - 2y + 24}{y-6}

According to standard algebraic procedures for subtracting rational expressions, which specific action did the colleague fail to recall?
