Question

Solve x^2 – 3x = –8
x= 3 +_ i sqrt 29 / 2
x= 3 +_ i sqrt 23 / 2
x= -3 +_ i sqrt 29 / 2
x= -3 +_ i sqrt 23 / 2

Answer 1

second one

Answer 2

3+/- sqrt(9-32) 3+/- sqrt(-23)
x_1,_2 = -------------- = ------------- = (3+/- i sqrt 23)/2
2 2

- your second answer is right

Answer 3

2nd answer is right
