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
