Write a quadratic equation with roots 2 - 3i and 2 + 3i.
I just need confirmation I did it correctly. I got y = x^2-4x+13

Your calculations are correct
(sum of roots = 2+3i + 2-3i = 4
product of roots = (2+3i)(2-3i) = 4-(-9) = 13 )
It said to write the quadratic <b>equation</b>, which is
x^2 - 4x + 13 = 0
you had y = x^2 - 4x + 13 , which is the quadratic <b>function. </b>
