Question 383298: Which of the following is the correct solution to the equation x^2-4x+6=0? Explain why the other solutions are wrong.
a) Solution 1
x = 4�(√4^2-4�1�6)/2
x = 4�√-8/2
x = 2�√-4
x = 2�2i
b) Solution 2
x = 4�(√4^2-4�1�6)/2
x = 4�√-8/2
x = 2�√-8
x = 2�2i√2
c) Solution 3
x = 4�(√4^2-4�1�6)/2
x = 4�√-8/2
x = 4�2i√2/2
x = 2�2i√2
