Question

Solve. Round your answer to the nearest hundredth.

x^2 + 45 = 0

Answer 1

slight problem here as this question will have a complex solution

Answer 2

\[x=\pm \sqrt{-45}\] which comes out pretty horribly...
\[x=\pm 6.708i\]

Answer 3

\[x = \pm i \sqrt{45}\]

Answer 4

x^2 + 45 = 0
x^2 = -45
x = √ (-45) or x = -√ (-45)
x = √(-1) * √45 or x = -√(-1) * √45
x = i √45 or x = -i √45
x = 6.71 i or - 6.71 i
