Question

Which constant number would be an to both sides of the equation rn order to complete the square for the quadratic function 1=x^2-6x

Answer 1

k = 9

Explanation:

Given

`1= x^2 - 6x`

Required

The perfect number

The coefficient c of x in the above equation is:

`c = -6`

Divide by 2

`c/2 = -3`

Square both sides

`(c/2)^2 = 9`

Hence, the constant to add is:

`k = 9`
