    Step-by-step explanation:

    x↑2-2x-3 = 0 is a quadratic equation.

    Solving for x

    x↑2-2x-3 = 0

    or, (x-1)↑2-4 = 0

    or, (x-1)↑2-2↑2 = 0

    or,(x-1-2) (x-1+2) = 0

    or, (x-3) (x+1) = 0

    or, x= 1 and 3

    Answer:

     {x}^{2}  - 2x - 3 = 0 \\  {x}^{2}  - 3x + x - 3 = 0 \\ x(x - 3) + 1(x - 3) = 0 \\ (x - 3)(x + 1) = 0 \\ x = 3 \: and \: x =  - 1

    hope this helps you
