Ready-for-Thanksgiving-Break Edition - November 17th

Algebra I

Today we discussed
Our discussion on multiplying polynomials moved into multiplying binomials (and the famous F.O.I.L.) mnemonic.  Keep in mind that when multiplying polynomials by polynomials, think to yourself how many multiplication problems you are actually having to do.  When multiplying, you must distribute all monomials throughout your expression.

(3x +2y)(x² + 3x + 4) à You are multiplying 2 monomials by 3 monomials for a total of 6 products!

(3x · x² ) +( 3x · 3x) +(3x · 4) + (2y · x²) + (2y · 3x) +( 2y · 4)

Pre-Algebra

Today we discussed
We continued our discussion of powers and bases and moved into dividing powers with the same base and the rules for handling these types of expressions.  Recall the main points from today's class:

Also recall that any number raised to the zero power is always one!

To be in simplest form, all negative exponents must be simplified.  A negative exponent is just a fraction!
