+1365 Combining all like terms and moving all terms to one side, we get
\(x^{2}+12x-4=0\)
The two roots of this are
\(x=2\sqrt{10}-6\\ x=-2\sqrt{10}-6\)
Squaring them we get
\(4\left(\sqrt{10}\right)^{2}-12\sqrt{10}-6\left(2\sqrt{10}-6\right)+\left(-2\sqrt{10}-6\right)^{2}\)
\(4\cdot 10-12\sqrt{10}-6\left(2\sqrt{10}-6\right)+\left(-2\sqrt{10}-6\right)^{2}\)
This simplifies to 152, which is our answer.
Thanks! :)
