Answer:
-13
Step-by-step explanation:
2x²+26x+156=0
x²+13x+78=0
x²+13x=-78
x²+13x+169/4=-143/4
(x+13/2)²=-143/4
x+13/2=(i√143)/2 or x+13/2=-(i√143)/2
x=(i√143)/2-13/2 or x=-(i√143)/2-13/2
(i√143)/2-13/2+(-(i√143)/2)-13/2=(i√143-13-i√143-13)/2=-26/2=-13

4 + 4 + 4 - 1 = 11? Was it supposed to be an equation? I am confused.
I’m sorry if I’m wrong but I do think your answer is X=22y^-1
Consider the polynomial 
It has three terms and their greatest common factor is 
Since
then
(you write in brackets the same sign as the corresponding term has).
Answer: correct choice is D.
