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)
