Answer: [tex]x=-4+3\sqrt{3} , -4-3\sqrt{3}[/tex]

Step-by-step explanation:

Move all the terms to one side

[tex]x^{2} +8x-11=0[/tex]

Use Quadratic Formula [tex]ax^{2}+bx+c=0[/tex]

[tex]x=\frac{-8+6\sqrt{3} }{2} ,\frac{-8-6\sqrt{3} }{2}[/tex]

Simplify the solutions

[tex]x=-4+3\sqrt{3},-4-3\sqrt{3}[/tex]

Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!
