Answer

The polynomial equation with real coefficients that has the given zeros \(3-5i\) and \(3+5i\) is \(\boxed{x^{2}-6x+34=0}\).

Steps

Step 1 :The roots of a polynomial equation with real coefficients always come in conjugate pairs if they are complex. This means that if \(3-5i\) is a root, then its conjugate, \(3+5i\), is also a root.

Step 2 :We can use these roots to form the polynomial equation by setting it up as \((x - (3-5i))(x - (3+5i)) = 0\).

Step 3 :Expanding this will give us the polynomial equation: \(x^{2} - 6x + 34\).

Step 4 :The polynomial equation with real coefficients that has the given zeros \(3-5i\) and \(3+5i\) is \(\boxed{x^{2}-6x+34=0}\).
