Answer:

Option 3 is correct that \(x^2-4x+5\)

Explanation:

To form a quadratic equation from its zeroes we have a formula which is

\(x^2-(sum of zeroes)x+product of zeroes\)

Here we have been give the two zeroes  \(x=2+i\) and \(x=2-i\)

substituting the values  \(x=2+i\) and \(x=2-i\) in the formula we will get

\(x^2-{(2+i)+(2-i)}x+(2+i)(2-i)\)

After simplifying the equation we will get \(x^2-4x+5\)      

Since, \(i^2=-1\)

Therefore required equation is :\(x^2-4x+5\)
