How many more unit tiles must be added to the function f(x)=x^2−6x+1 in order to complete the square?
1
6
8
9

f(x)= x^2 -6x +1

In order to Complete the square

F(x) can be rewritten as

x^2 - 2× 3x + 1

Now As coefficient of x^2 is 1 and coefficient of x is 3

We need 3^2 =9 as constant term

As Constant term= 1

So we need to add 8 to make it perfect square

Finally, 8 more unit Tiles must be added to function in order to complete the square

8
