Using algebra tiles to factor polynomials

Using algebra tiles to factor polynomials

Algebra tiles can be used to represent polynomials. We can also use those tiles to solve polynomials. In this lesson, we will try to solve some polynomials using algebra tiles.
Basic Concepts: Model and solve one-step linear equations: ax=bax = b, xa=b\frac{x}{a} = b, Solving two-step linear equations using addition and subtraction: ax+b=cax + b = c, Solving two-step linear equations using multiplication and division: xa+b=c\frac{x}{a} + b = c, Solving two-step linear equations using distributive property: a(x+b)=c\;a\left( {x + b} \right) = c
Related Concepts: Determining number of solutions to linear equations, Solving systems of linear equations by graphing, Solving systems of linear equations by elimination, Solving systems of linear equations by substitution
