Question 2

Answer 1

Answer:

9

Step-by-step explanation:

you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.

So we would need to realize that the constant would be equal to (-6/2)^2  =(-3)^2 = 9

We have completed the square.

f(x) = 4*( x - 3)^2  + 20   is now in Vertex Form
