Question

Solve using the square root method. Round to the nearest tenth, if necessary.
x2 + 17 = 0

Answer 1

\[x^2 + 17 = 0\]
\[x^2 = -17\]
\[\sqrt{x^2} = \sqrt{-17}\]
\[x = \sqrt{-17}\]
\[x = i\sqrt{17}\]

Answer 2

\[x^2 + 17 = 0 \rightarrow x^2 =- 17 \rightarrow x =\pm \sqrt{-17} \]
i.e. \[x =\pm \sqrt{-1 \times17} \rightarrow x =\pm \sqrt{-1} \times \sqrt{17}\]
\[x =\pm i \sqrt{17}\]
