Answer:

[tex]f(x)=(x-1)^2-6[/tex]

Step-by-step explanation:

The given quadratic function is

[tex]f(x)=x^2-2x-5[/tex]

We complete the square to obtain the vertex form;

Add and subtract half the coefficient of [tex]x[/tex]

[tex]f(x)=x^2-2x+(-1)^2-(-1)^2-5[/tex]

Factor by identifying the perfect square

[tex]f(x)=(x-1)^2-1-5[/tex]

Simplify to obtain the vertex form as

[tex]f(x)=(x-1)^2-6[/tex]
