Verified Answer :

apologiabiology

make one side equal zero
minus 11 to both sides
x^2-6x-2=0
another quadratic equation

if you hahve
ax^2+bx+c=0
x=\(\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}\)

1x^2-6x-2=0
a=1
b=-6
c=-2

x=\(\frac{-(-6)+/- \sqrt{(-6)^{2}-4(1)(-2)} }{2(1)}\)
x=\(\frac{6+/- \sqrt{36+8} }{2}\)
x=\(\frac{6+/- \sqrt{44} }{2}\)
x=\(\frac{6+/- 2\sqrt{11} }{2}\)
x=\(3+/- \sqrt{11}\)
x=\(3+ \sqrt{11}\) or \(3- \sqrt{11}\)

aprox
x=6.31662 or -0.316625
