Answer:

Option C

$x={1(+/-)2\sqrt{3}}$

Step-by-step explanation:

we have

$x^{2}-2x-11=0$

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}-2x-11=0$

$a=1\\b=-2\\c=-11$

substitute

$x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-11)}} {2(1)}$

$x=\frac{2(+/-)\sqrt{4+44}} {2}$

$x=\frac{2(+/-)\sqrt{48}} {2}$

$x=\frac{2(+/-)4\sqrt{3}} {2}$

$x={1(+/-)2\sqrt{3}}$
