Question 1

Completer the square purpose

Answer 1

To go from y=ax^2 +bx+c to

y=a(x-h)^2+k

Question 2

How to find h part of complete the square

Answer 2

H= -b/2a

Question 3

How to find k in complete the square

Answer 3

H^2 + k= c

Or
K= c-h^2

Question 4

How to find max of a quadratic

Answer 4

Find the vertex

-b/2a and then solve for x
