Question

4 + x + X2 = 0 by completing square method​

Answer 1

Answer:

HOPING THAT YOU KNOW THE METHOD.

Step-by-step explanation:

x^2 + x + 4 = 0

x^2 + x + 1/4 - 1/4 + 4 = 0

(x + 1/2)^2 -1/4 + 4 =0

(x + 1/2)^2 + 17/4 = 0

(x + 1/2)^2 = -17/4

(x + 1/2) = +-√(-17/4)

x = -1/2 +-√(17/4) i i means iota = √(-1)

x = (-1 +- √17 i)/2
