What are the 2 steps of completing the square?

1. Make the coefficient of x² is 1 by factorization

2. Use the formula…

What is the formula for completing the square?

(x + b/2 )² - (b/2)² + c

How do you find the max or min points from the completed square?

(x + b/2)² = 0 will give the x-coordinate

-(b/2)² + c will give the y-coordinate

What do you do with the square brackets at the end?

Factorize through
