1. Order of factoring
Putting INTO bubbles:

• -GCF
• -DOTS
• -Trinomial
• -Sum/Diff of Two Cubes
• -Grouping
• -Check Again
2. difference of two squares
u^2 - v^2 = (u+v)(u-v)
3. perfect square trinomial
u^2 + 2uv + v^2 = (u+v)^2
4. test for perf. square tri
5. sum/diff two cubes
(u^3 + v^3) = (u+v)(u^2 - uv + v^2)

(u^3 - v^3) = (u-v)(u^2 + uv + v^2)
6. simplifying
taking out of bubbles into larger form
7. square of a binomial
• (u+v)^2 = u^2 + 2uv + v^2
• square double square
8. cube of a binomial
(u+v)^3 = u^3 + 3(u^2)v + 3u(v^2) + v^3
9. vertex of a parabola
(-b/2a, f(-b/2a))
10. x-int and y-int
• x-int (a,0) because y=0
• y-int (0,a) because x=0
11. form for a circle
(x-h)^2 + (y-k)^2 = r^2
12. symmetries
• x-axis: (x,y) -> (x,-y)
• y-axis: (x,y) -> (-x,y)
• origin: (x,y) -> (-x,-y)
13. order of transformations
• Horizontal Shift
• Reflection
• Stretch/Compression
• Vertical Shift
• (ABC Order)
14. direct and inverse
• direct: kx=y
• inverse: xy=k
• always assume direct
15. standard form of a quadratic
• f(x) = a(x-h)^2 + k
• Vertex is (h,k)
