Assessing Student Thinking | Texas Instruments
...ver, when prodding him a bit more by asking how he would solve the problem using his method if a 2 was placed in front of the first term, Joey had no idea what he would do. The “trick” he was using was only valid for solving quadratic equations with a lead coefficient of 1. He wasn’t even sure wh...https://education.ti.com/en/bulletinboard/2023/assessing-student-thinking
