1):

We use the quadratic formula

 \(\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:1\cdot \left(-11\right)}}{2\cdot \:1}\)

 

We then simplify this quadratic formula into this\(\frac{-\left(-6\right)\pm \:4\sqrt{5}}{2\cdot \:1}\)

 

\(3+2\sqrt{5},\:x=3-2\sqrt{5}\)            The final answer is to the left. Hopefully this helps  smiley

 

Didn't provide all the steps sorry.
