This video simplifies (x^3+ 3x - 6) + (-2x^2 + x - 2) - (3x - 4).

In this lesson, students use the distributive property to multiply a monomial by a polynomial and understand that factoring reverses the multiplication process. Students use polynomial expressions as side lengths of polygons and find area by multiplying. Students recognize patterns and formulate shortcuts for writing the expanded form of binomials whose expanded form is a perfect square or the difference of perfect squares.

Using tiles to represent variables and constants, learn how to represent and solve algebra problem. Solve equations, substitute in variable expressions, and expand and factor. Flip tiles, remove zero pairs, copy and arrange, and make your way toward a better understanding of algebra.

Find remainders, by using long division and the Remainder Theorem, to help decipher a message.

Students explore this interactive math tool and try to figure out what's happening on their own to discover the value of (a + b)^2?

Students will draw on their foundation of the analogies between polynomial arithmetic and base-ten computation, focusing on properties of operations, particularly the distributive property. Students identify and make connections between zeros of polynomials and solutions of polynomial equations.

Students will look at multiplying monomials, then monomials by
polynomials and finish with polynomials by polynomials.

In this video, students quickly review what polynomials are, common related terms (e.g. degree, coefficient, binomial, etc.), addition & subtraction of polynomials, and modeling area with polynomials.

Students will analyze and explain precisely the process of solving an equation. Through repeated reasoning, students develop fluency in writing, interpreting, and translating between various forms of linear equations and inequalities and make conjectures about the form that a linear equation might take in a solution to a problem.

This video simplifies (4x^2y - 3xy + 25) - (9y^2x + 7xy - 20).
