Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$

then the quadratic formula is

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given equation is

$0=x^2-2x-3$

Here, a=1, b=-2 and c=-3.

Substitute these values in the above formula.

$x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}$

$x=\frac{2\pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}$

Therefore, the correct option is 1.
