Multiplying polynomials Video transcript Multiply negative 4x squared by the whole expression 3x squared plus 25x minus 7. So if you multiply anything times a whole expression, you really just use the distributive property to multiply each term of the expression by the negative 4x squared. So we're going to have to distribute this negative 4x squared over every term in the expression. So first, we could start with negative 4x squared times 3x squared.
Look for and make use of structure. Warm Up Developing a Baseline I plan to ask students to work with their partner on this warm-up. While students are working, I circulate around the room to assess student understanding of the concepts and procedures. When students have completed the warm-up, I will call on different students to show their answers either on the board or using the document camera.
As usual, I encourage students to thoroughly explain their answers to the class MP3. I display the rubric for students to see and explain its levels to them.
Once the plan is explained, I divide the class up into four groups: I also try to keep in mind the groups that they will end up forming the following day. Since there will be one student from each of the expert groups, I try to balance the groups appropriately. If the number of students in class is not a multiple of 4, I put any extra students into groups 2 and 4.
Concepts from Groups 1 and 3 are often reiterated by Groups 2 and 4. For the next portion of the lesson it would be ideal to have computing available either tablets or laptops. If students need to share technology that will work, but it is not ideal.The easiest case of polynomial multiplication is multiplying a monomial and a polynomial.
In this case, we "distribute" the monomial to each term in the polynomial. We really do distribute it, though. We weren't using the quotation marks to be sarcastic or ironic. Menu Algebra 1 / Factoring and polynomials / Monomials and polynomials.
A polynomial as oppose to the monomial is a sum of monomials where each monomial is called a term. The degree of the polynomial is the greatest degree of its terms. Don't forget to reverse the signs within the second parenthesis since your multiplying all terms with Multiply Polynomials - powered by WebMath.
