Quizplus · Accepted Answer

The correct factoring by grouping for the expression $xy + y + 4x + 4$ is to first group the terms as $(xy + y) + (4x + 4)$, then factor out the common factors from each group, which gives $y(x + 1) + 4(x + 1)$. Finally, factor out the common factor $(x + 1)$, resulting in $(x + 1)(y + 4)$.
