Given data:
The given expression is x^2 + 4x = 8 .
The given expression can be written as,
[tex]\begin{gathered} x^2+4x-8=0 \\ x=\frac{-4\pm\sqrt[]{(4)^2-4(1)(-8)}}{2(1)} \\ x=\frac{-4\pm\sqrt[]{48}}{2} \\ =-2+\frac{\sqrt[]{48}}{2},\text{ -2-}\frac{\sqrt[]{48}}{2} \end{gathered}[/tex]
Thus, the option (A) is correct.
