Wiki/Email Questions
• Multiply Polynomials
When do students multiply polynomials such as (π‘₯ + 1)(π‘₯ + 2)?
Wiki/Email Questions
• Imaginary numbers
I see that we teach imaginary numbers prior to teaching students about
quadratic equations, factoring, etc. Should this be reversed?
Wiki/Email Questions
• Conditional Probability and the Rules of
Probability
I don’t see the CP standards from Analytic Geometry in my copy of the
Accelerated CCGPS Analytic Geometry B / Advanced Algebra standards,
are we supposed to teach them?

Examples & Explanations
A biology student is studying bacterial growth, She was
surprised to find that the population of the bacteria doubled
every hour.
Complete the following table:
Adapted from Illustrative Mathematics N-RN Extending the Definitions of Exponents, Variation 2
Examples & Explanations
The student conducting the study wants to create a table with
more entries; specifically, she wants to fill in the population at
each half hour. However she forgot to make these
measurements so she want s to estimate the values.
Complete the following table:
Adapted from Illustrative Mathematics N-RN Extending the Definitions of Exponents, Variation 2
Examples & Explanations
What if the student wanted to estimate the population every 20
minutes instead of every 30 minutes. What multiplier would be
necessary to be consistent with the population doubling every
hour?
