Please matke as branliest.I only want one more branliest mark.

Answer 2

Answer:

x= -1+sqrt(14)i ,-1-sqrt(14)i

Step-by-step explanation:

x={-b+- sqrt(b^2-4ac)}/2a

where a=1 b=2 c=15

x={-2+-sqrt(4-4(1*15)}/2*1

x={-2+-sqrt(4-60)}/2

x= {-2+-sqrt(-56)}/2

x={-2+-2sqrt(14)i}/2

x= 2{-1+-sqrt(14)i}/2

x=-1+-sqrt(14)i

x= -1+sqrt(14)i ,-1-sqrt(14)i
