Question 625141: One zero of the function is -4, find the others.
f(x)=x^3-2x^2-11x+52
Answer by oscargut(2103) (Show Source): You can put this solution on YOUR website!
f(x)=x^3-2x^2-11x+52
1 -2 -11 52
-4 -4 24 -52
1 -6 13 0
x^2-6x+13 =0
x = [6 +- sqrt(-16)]/2
= [6+-4i]/2
3+-2i
Answer: remaining zeros are: 3+2i and 3-2i
