For an activity in class, the teacher gave each student a small card with a binomial on it. While music played for a few seconds, students walked around the room. When the music stopped, the students paired with the person nearest to them. Elinor’s card had 3x + 4 on it. She paired first with Mike whose card showed -2x – 1. The teacher asked the students to add, subtract, and then multiply the binomials on their two cards together and then record their solutions on a white board. Which of the following could not be one of this pair of students’ answers? x + 3
