The forth concept was ‘Factor Theorem and Identifying Zeros of the Polynomial Function’ where students learned the Factor Theorem to identify the zeros of a polynomial function. In this lesson teacher designed the instructional tasks involving a various degrees of polynomials.

A consequence of the Remainder Theorem is to establish the equivalence between linear factors and zeros that is the basis of much work with polynomials in high school: the fact that p a =0 if and only if x - a is a factor of p ( x ) . It is easy to see if x - a is a factor then p a =0 . But the Remainder Theorem tells us that we can write

0.3 Operations on Polynomials. Adding and Subtracting Polynomials . An expression of the form is called a Polynomial, where , … , are real numbers and . The degree of a polynomial is the highest power of the variable. Thus, , , and are polynomials of degree 1, 2 and 4, respectively. Polynomials can be added by combining similar (or like) terms.

Also teach students how to factor out the greatest common factor (GCF) in those problems where a common factor could be factored out first. For example, to factor since each term in the product is divisible by the factor 2, simply factor out the 2 from each term first, thus giving 2(and then to completely factor the expression ( to get the ...
How to Factor a Cubic Polynomial: 12 Steps (with Pictures)
(x – a) is a factor of f(x) The point (a, 0) is an x-intercept of the graph of f(x) if x= a is a real number. The Factor Theorem: Using Division Results To Factor and Find Zeros. If f(x) divided by (x – c) results in zero remainder, then we can say that x = c is a zero. Also, we can say that (x – c) is a factor.

While dividing a polynomial by a given factor to find a missing factor is easily accessible, factoring without knowing one of the factors is challenging. Students recall the work with factoring done in Algebra I and expand on it to master factoring polynomials with degree greater than two, emphasizing the technique of factoring by grouping.

We can easily derive a recursion relation among these sums. Consider Sp(n+1). From the definition for p>0, Sp(n+1) = ip. Rewrite this sum in two different ways. First, split off the largest term: Sp(n+1) = np + ip = np + Sp(n) Alternately, replace the summation index by defining i:=j+1 : Sp(n+1) = (j+1)p = 0p + (j+1)p
