1. To prove that the difference of squares, z² - y², can be factored into polynomials with real coefficients, begin with a diagram of a square of side length
cut from one corner.
y
with a smaller square of side length ²
2. Cut the diagram into Rectangle #1 with dimensions z by y
and Rectangle #2 with dimensions zbyz-y-
Rectangle #2
Rectangle #1
