Question 1024341
.
Write the quadratic equation with a lead coefficient of 1 whose roots are 1+4i and 1-4i. -- I got part of it I believe, but got stuck. An explanation of how to completely solve would be great, thank you :)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
The quadratic polynomial is (x - (1+4i))*(x - (1-4i)).


You can transform it further


= ((x-1) -4i)*((x-1) +4i) = {{{(x-1)^2 -16*(i^2)}}} = {{{x^2 - 2x + 1 + 16}}} = {{{x^2 - 2x + 17}}}.
