X^2+6x=-22 witch of the following is a solution

x1=-3+i*sqrt (13)

x2=-3-i*sqrt (13)

Step-by-step explanation:

x^2 + 6x=-22

x^2 + 6x+22=0 (Quadratic equation)

a=1, b=6, c=22

x1 = (-b+sqrt (b^2-4ac)) / 2a

x1 = (-6+sqrt (6^2 - 4*1*22)) / 2*1

x1 = (-6+sqrt (36-88)) / 2

x1 = (-6+sqrt (-52)) / 2

x1 = (-6+sqrt (52i^2)) / 2 ... i^2=-1

x1 = (-6+sqrt (4*13i^2)) / 2

x1 = (-6+2i*sqrt (13)) / 2

x1=-3+i*sqrt (13)

x2 = (-b-sqrt (b^2-4ac)) / 2a

x2=-3-i*sqrt (13)
