Multiplying binomials is a skill with many applications. With PARCC, it can be tested by asking students to find the quotient of 2 binomials.

How can you factor a polynomial when you don’t even know what the polynomial is? Well, you can’t, but you can know a few things.

We sometimes need to develop mathematical models for costs we incur in our jobs or in daily life. Here’s one way to do just that.

Given a few facts about the total sales at a business over 3 years, can you find the basis sales figures using algebraic manipulation?

Graphing the solution to a system of linear inequalities is likely to come up on the PARCC test in algebra 1. Are you ready?

Measures of central tendency and the spread of data, including outliers, will come into play as students take the PARCC test in algebra 1 this spring.

Creating 2 equations in 2 unknowns to describe a set of conditions is a skill algebra 1 students need if they’ll be taking the PARCC test this spring.

How would you figure out (and explain) when one car, traveling at a given speed, will overtake another car that had a head start?

Adding, multiplying, & subtracting polynomials is tested, quite thoroughly, on the PARCC algebra 1 test, used in Md. and some middle schools in IL.
