A Reflective Comment

I liked learning about turning x^2+6x+9x into (x+3)^2. This was very cool because of the relationship between the b and c values. The equation that represents this relation I like to write as b/2=√c. In this problem 6/2 is 3 and the √9 is also 3. This doesn't work with every quadratic but for every quadratic that factors into a(x+h)+k.
