Question

Solve:
p2 + 20p + 200 = 0

Answer 1

you are asking the question which is in complex side...just use formula as
ax^2 + bx +c=0
then x= (-b+(square root D))/2a where D is discriminant ....D=square root of(b^2 - 4ac) if your D came neagative means your ans is in complex from..use square root (-1)=i
