Question 744171: Looking to write a quadratic equation in the form ax^2+bx+c=0 , having roots of 1+i and 1-i. Not good with the "i" usage. Does below look correct?
For X1 I foiled (1+i)(1-i) to get -1
X2 would be it's conjugate, 1
Using quadratic equation (x-x1)(x-x2) I came up with x^2+0x-1=0
Thanks for your help!
