using the identity e of data minus the of negative data over to this sign h of data. We know we have either the X plus y plus e to the negative X plus y recall where the night it is on the outside of the E divided by two. Now we know this is equivalent to eat the axe, even negative acts over two times either. Why cost you the negative? Why over too plus even the X minus, even the negative X over too times either. Why Honesty to the negative? Why over too And this simplifies to co sign. H acts Corson Age. Why? Because sign age acts Sign age. Why?
