The polynomial represented by the algebra tiles might depend on the arrangement of positive and negative tiles. For \( 2x^2 - 4x - 6 \), you would see two large square tiles for \( 2x^2 \), four rectangular rods or tiles in the negative direction for \( -4x \), and six unit tiles negated for \( -6 \). This creates a visual representation of how the coefficients affect the overall structure. When working with algebra tiles, a common mistake is misunderstanding the use of negative tiles. Ensure that every negative coefficient corresponds to a correctly placed negative tile. For example, ensure that if you say “-4x,” you indeed have four tiles that represent a loss or removal, not just a misplacing of positive tiles which could confuse the resulting expression!
