Algebra+Submersion

Algebra topics you need to be VERY skilled at in order to be successful in Algebra 2 include all of the following :

1) QUADRATIC FORMULA When you see an Algebra problem that involves x squared, think QUADRATIC FORMULA! It is one of the most valuable tools you have (therefore, it should be memorized). We will use the quadratic formula often! Try these with your group:

a) 3x^2 – 4x – 8 = 0  c) 2x^2 + 11x = 7

b) Find x-intercepts: y = x^2 + 9x + 3 d)  (x + 3)^2 – 19 = 13x

2) GRAPHING
 * Graph: y = x^2 + 11x + 24 ||



I think most of you are good at graphing __lines__. Soon it will be very important that you can expertly graph __parabolas__ and other functions as well. Remember: You can ALWAYS make a table of values.

3) SYSTEMS of equations When we solve a system, we are looking for the point (or points) of intersection between 2 graphs. We might use substitution, elimination, or even another method. Try these out:

a) y = 2x + 6 -- y = 3x – 7

b) 5x + 3y = 16 2x + y = 12

4) LAWS of EXPONENTS Exponents and how they work… this is very often misunderstood. Simplify all of the following:

a) (x^3y^5)(x^7y^13)

b) (2x^3)^4
