Question

Solve for the variable. Show all work.22 – 13 = -1

Answer 1

Given the equation for this expression

`\begin{gathered} x^2\text{ - 13 = -1} \\ x^2\text{ = -1 +13} \\ x^2\text{ = 12} \end{gathered}`

The value of x

`\begin{gathered} x^2\text{ = 12} \\ \text{square root both side} \\ x\text{ = }\sqrt[]{12} \\ x\text{ = 2}\sqrt[]{3} \end{gathered}`

Hence the value of x = 2√3
