Ingrid and Harish were trying to solve the equation:
22 - 3x = x + 1
Ingrid said, "First, I'll subtract x from both sides so I have a? - 4x = 1. Then I can solve by completing the
square. If I add 4 to each side, I can rewrite the equation as (x - 2)² = 5."
Harish said, “I'll isolate the xạ term by adding 3x to both sides of the equation. Then I'll solve by taking the
square root."
Whose solution strategy would work?
