Which of the following is equivalent to the quadratic equation below after completing the square?
x^2+4x=0
a. (x+4)^2=4
b.(x+2)^2=16
c.(x+4)^2=8
d.(x+2)^2=4

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
