Answer 1

@Hero @ParthKohli @whpalmer4

Answer 2

do the same thing you did to solve the previous problems. the only difference is that you'll have a square root of a negative number, and \[\sqrt{-x} = i\sqrt{x}\]where \(i = \sqrt{-1}\)

Answer 3

All I got was there was no solutions.

Answer 4

how did you solve it?

Answer 5

Completing the square. What I got now was
x=1/7(-1+2isqrt5) and x=1/7(-1-2isqrt5)
