3.  GCF  x 2 + 2x =  Perfect Squares  A 2 - B 2 =  Product Sum  x 2 – 3x + 4 =

5.  X a * X b =  X a / X b =  (X a ) b =  X -a =

7.  Create 2 Equations!  One positive!  One negative!  The distance from zero!

9.  If you divide or multiply by a negative number, when solving an inequality, make sure you FLIP THE SIGN!!

11.  Elimination Method  Adding two equations together  Substitution Method  Substituting one variable for the other ▪ One equation must be set equal to one of the variables  Set both equations equal to each other  If both equations are equal to the same variable.

13.  Direct: y = kx  Inverse: y = k/x

14.  If c and d are inversely proportional and c = 10 when d = 6, what is d when c = 30
