Han was solving the equation x² + 6x – 10 = 0 by completing the square, and he wrote: x? + 6x - 10 = 0
x? + 6x = 10
x? + 6x + 36 = 46
(x + 3)2 = 46
x+3 = V46
x=-3 + 746
1. Han made a mistake. What was it?
2. Using the math equation editor, show how to solve the problem correctly.
(You may also show work on a piece of paper and upload a photo of your
work).
