document.write( "Question 669665: The stated problem: Given that the polynomial function has the given zero, find the other zeros. f(x)= x to the third minus 4x squared + 14x -20; the given zero is two.
\n" ); document.write( "I am able to get to the end by using division or synthetic division with a final quotient of: x squared -2x+10 then use that in a quadratic equation and end with 2 + or - 6 divided by two. My answer (which is wrong is 1+3, 1-3)The correct answer is 1+3i & 1-3i & of course -2. I don't understand. Please if you can, explain. Thanks!
