When it comes to constraints on real-world systems, nothing does the trick like linear algebra. Here, a factory makes and packages salsa.

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

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.

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.

Solving equations for a variable of interest is required in algebra 1 on the PARCC test (and in the Common Core). Students find the radius of a circular pool.

Is a given ordered pair on the graph of a function? Algebra 1 students should be able to figure it out, esp. those who will take the PARCC test this year.

The zeros of a polynomial are the *x* values when the polynomial equals 0. Do you know how to find the zeros?
