Question

Solve the following equation for x..
`5x { }^(2) = 180`

Answer 1

`\begin{gathered} 5x^2=180 \\ x^2=(180)/(5) \\ x^2=36 \\ x=\sqrt[]{36} \end{gathered}`

The square root of 36 has 2 results, one positive and one negative.

`\begin{gathered} x=\sqrt[]{36} \\ x=\pm6 \\ or \\ x_1=6\text{ and }x_2=-6\text{ } \end{gathered}`
