Zeros of Polynomials

Develop a strategy for solving quadratic equations. Pupils learn to factor quadratic equations and then apply the Zero Theorem. The instructor explains the Zero Theorem in detail.

Though Sal expects viewers to be "reasonably familiar" with square roots, he takes this opportunity to explain some of the notation and how to graph square root functions. He uses a graphing calculator from my.hrw.com/math06 to...

Why does an exponent of zero result in a value of one? Give your classes a concrete explanation for this property that many struggle to remember. A video lesson provides an explanation and provides examples of exponential expressions...

Zero in on a commonly mistaken property. The video instructor shows several examples of expressions raised to the power of zero. Each example incorporates a different exponent property and highlights common misconceptions.

Some lessons feature videos, some interactive practice problems, and some have notes and activities. This comprehensive look at factoring and solving polynomial equations using the zero product principle has all of this and more. Though...

The zero of a function is the x-value of a function that makes a function equal zero. I know, it sounds confusing. So watch this video as the teacher demonstrates what this means.

There is one exception to this rule, but all numbers that have a power of zero equal one. Don't believe it? Watch this video as the instructor breaks it down to prove this to be true. This makes solving a problem with a zero exponent...

Jim Yang does a great job clearing up any issues learners might have when dealing with zero as a denominator. This clip is clear, well done, and makes sense. Use at an independent work station or send home as a helpful tutorial.

Working with a zero exponent makes an expression very easy to figure out, yet it comes with some special rules. Watch this tutorial for guidance when working with a zero exponent. [7:08]
