DescriptionIn the seventh clip in a series of nine from the first of seven interviews focusing on Early Algebraic Ideas about the binomial expansion, Stephanie uses the distributive property to determine that x(x + y) + y(x + y) can be expressed as x*x + x*y + y*x + y*y (with * signifying multiplication). When asked by the researcher, Carolyn Maher, whether this expression can be simplified, Stephanie is uncertain about how to combine terms or parts of terms.
