Explore finding zeros of polynomial functions in a number of ways including using synthetic division, depressed polynomials, factoring, the Factor Theorem. and the Rational Roots Theorem.  This lesson also looks at complex conjugates as zeros of a polynomial function. 
Solve polynomial equations of degree using different theorems and apply the zero factor theorem for unknown numbers in a quadratic equation. Also use the discriminate to find out the kind of solutions to given quadratic equations shown.
In this remainder and factor theorems activity, 11th graders solve and complete 10 different problems. First, they divide using synthetic division and write their answer in the form given. Then, students use synthetic division to find the value of each function. They also find the remaining factors of each polynomial.
In this synthetic substitution learning exercise, students evaluate three different function at specified points.  Students also determine if given factors are factors of four specific polynomials.  Additionally students use the Factor Theorem and synthetic division to determine rational roots for thirteen polynomial functions.
This comprehensive lesson looks at higher-degree polynomials. The important topics covered include the Remainder Theorem, the Factor Theorem, and synthetic division. Included is a clearly written tutorial, problem sets, summary, and answer key. 
This algebra worksheet reviews writing polynomials in standard form from factored form, looks at the graphs of polynomials of degree higher than two, and identifies the zeros of polynomials using the Factor Theorem and Fundamental Theorem of Algebra.   
Explore the concept of polynomial division and make conjectures about the Remainder and Factor Theorems in this investigative worksheet. Learners  use a CAS calculator to factor polynomials through polynomial division. 
High schoolers factor polynomials and linear functions and apply concepts of the fundamental theorem of algebra to solve problems. They graph their solutions and analyze the graph.
In this remainder and factor theorems worksheet, one solves and completes 24 different types of problems. First, they use synthetic substitution to find the value for each function. Then, students find the remaining factors of the polynomials listed.
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.
In this polynomial activity provides extra practice the Factor and Remainder Theorems. They identify factors of given linear expressions. This two-page activity contains 19 problems. The answers are provided on the second page.
In this Algebra II/college level activity, students use long and synthetic division to divide polynomials and use the Factor Theorem to show that a given polynomial is a factor of a polynomial function.  The two page activity contains forty-four problems.  Answers are included. 
Students factor polynomials and use long division t solve problems. In this algebra lesson, students find the zeros of polynomials by synthetic and long division. They perform operation using complex numbers.
Need a quick self-checking worksheet on finding factors and zeros of higher-degree polynomials?  Here are five questions that test ones use of synthetic division and the Remainder Theorem to determine quotients, remainders, and factors of polynomials.  
This activity uses the division algorithm and the definition of a zero/root of a function to guide your class to see the relationship between zeros and factors of a general quadratic, which can later be generalized to the Remainder Theorem. All three problems can be used as part of a lesson, or the first two as part of an assessment. Included are detailed solutions and helpful hints for the teacher.
This activity highlights the use of the remainder theorem to solve for the unknown coefficient of a specified polynomial when given one of its factors. Use this single problem as a warm-up exercise, a quick check-in at the end of a lesson, or as one problem on a longer assessment.
Investigate the Remainder Theorem in this algebra lesson. Explore the relationship between the remainders of polynomial division and the function. Each of the four problems gets progressively more complicated. This might be a great lesson to do as a whole class using a teacher's CAS  computer software if students don't have a CAS version of the TI-Nspire. 
In this investigative instructional activity, a programmable calculator is used to help learners explore the properties of irrational numbers. Here, the square root of 2 is calculated to a large number of decimal places by using an iterative algorithm the converges to value of the square root of two. 
In this trigonometry worksheet, students solve for trigonometric functions. They convert between radians and angles using the properties of sine, cosine and tangent. There are 30 problems on this handout.
Students explain the relationship between linear factors of a polynomial function and the graph of the function. Based on the graph of two lines, they sketch the parabola that is the product of the two linear expressions.
