Question 428150
Find the polynomial with the lowest degree having the following zeros -2, 2-i
--------
Complex roots always occur in pairs, so add 2+i as a zero
--> (x+2)*(x-2-i)*(x-2+i)
= {{{(x+2)*(x^2 - 4x + 5)}}}
= {{{x^3 - 2x^2 - 3x + 10}}} --> E
---------------
A)x^3+6x^2+10
B)6x^2+13x+10
C)x^3+6x^2+13x+10
D)x^3+2x+3x-10
E)None of the above
