Geometric Investigation of (a+b)^2
Curator: Stephanie Donelko
This Illuminations activity depicts a geometric representation of (a+b)^2 in order to show that the expanded version does not equal a^2 + b^2. One can manipulate the size of lengths (a) and (b) by moving the slider. The technology displays the dimensions of the square as well as the expanded area of the square.
