6
Step-by-step explanation:
Answer:
x = 7/2 ± 3/2*(i√3)
Step-by-step explanation:
The equation is
(x - 5)^2 + 3(x - 5) + 9 =0
Let A = (x-5)
The equation becomes now
(A)^2 + 3(A) + 9 =0
We then apply the quadratic formula
A = [-(3) ± √((3)^2-4(1)(9)) ]/ (2(1))
A = -3/2 ± 3/2*(i√3)
Now, we revert the substitution
(x-5) = -3/2 ± 3/2*(i√3)
x = 7/2 ± 3/2*(i√3)
