## Modeling Polynomials

For the Algebra tiles red are positive and everything else are negative.  $(x-1)^2$ $x^2-2x+1$  $(x+1)^2$ $x^2+2x+1$  $(x-1)(x+1)$ $x^2-1$

The fourth question can not be represent by algebra tiles but by the rules I can fond out the simplist form of the equation. $(x-1)^3$ $x^3-3x-1$
