Approximating Roots of Polynomials

Pair this resource with a reading of any math textbook, article, or book. Learners take note of unknown words and use the provided graphic organizer in order to use word roots, prefixes, and suffixes to help them determine the meaning of...

Familiarize young mathematicians with the radical concept of square roots using this set of skills practice problems. Building on prior knowledge about combining like terms in algebraic expressions, this learning exercise helps students...

Sharpen the factoring skills of young algebraists with this skills practice worksheet. Focusing on the long division of polynomials, these problems challenge students to factor, graph, and describe polynomials of varying degrees.

You mean the square root of five and five don't have the same value? Learners estimate the value of irrational roots. As they practice estimating the value, they increase their understanding of roots. The lesson is the fourth in a series...

Consider complex numbers, roots, and quadratic equations. Use the discriminate as a way to determine the nature of a quadratic's roots. Then discuss the similarities and differences between quadratics with two, one, or no real roots....

Investigate the relationship between irrational roots and a number line with a resource that asks learners to put together a number line using radical intervals rather than integers. A great progression, they build on their understanding...

Who doesn't need to know the Fundamental Theorem of Algebra? Use the theorem to find the roots of a polynomial on a TI calculator. The class explores polynomials with one solution, no real solutions, and two solutions. This less lesson...

Investigate the Fundamental Theorem of Algebra and explore polynomial equations to determine the number of factors, the number of roots, and investigate multiplicity of roots.

Using your graphing calculator, find all the rational zeroes of a polynomials by using the Rational Zero Theorem. Divide polynomials using the Remainder Theorem and the Factor Theorem and then graph it to find the number of real roots.

Young mathematicians explore the concept of solutions to higher order equations as they find roots of polynomials of degree three or higher. They also use the zero function on the Ti-83 to locate zeros of polynomials on a graph.
