  1. |x +b| = c
    • -b is the centerpoint
    • x is exactly c units away from b
  2. |x + b| < c
    • -b is the centerpoint
    • x is less than c units away from the centerpoint, -b
  3. with fractions rx blank as x blank
    rx decreases as x increases
  4. sqrt(x) =
    |x|
  5. (a2 - b2 ) =
    (a + b)(a - b)
  6. (x + y)2 =
    x2 + 2xy + y2
  7. (x - y)2 =
    x2 - 2xy + y2
  8. (x + y)(x - y)=
    x2 - y2
  9. (n2 - 1)
    • = (n2 - 1)
    • = (n2 - 12 )
    • = (n + 1)(n - 1)
  10. n(n2 - 1)
    • = n(n2 -1)
    • = n(n2 -12 )
    • = n(n+1)(n-1)
    • = (n-1)n(n+1)
    • 3 consecutive integers
