Answer

x = 3 ± i

x = (3 + i)

OR

x = (3 - i)

Step-by-step explanation

To solve this, we need to note that √(-1) = i

So, for this simplification

√(36 - 40) = √(-4) = √[(4)(-1)] = 2i

We can now fully simplify the expression given


\begin{gathered} x=\frac{6\pm\sqrt[]{36-40}}{2} \\ =(6\pm2i)/(2) \\ =(6)/(2)\pm(2i)/(2) \\ =3\pm i \end{gathered}

x = 3 ± i

x = (3 + i)

OR

x = (3 - i)

Hope this Helps!!!
