$F i r s t o f a l l t a k e s u m o f (z^{2} + y z - y^{2}) + (3 y^{2} - z^{2}) & (y z + 2 z^{2}) + (2 y^{2} + 3 y^{2}) + (- y^{2} - z^{2} - y z) = y z + 2 y^{2} & y z + 2 z^{2} + 2 y^{2} + 3 y^{2} - y^{2} - z^{2} - y z = y z + 2 y^{2} .... (i) & z^{2} + 4 y^{2} ......... (i i)$

Now, Subtract (i) from (ii), we get,

$= z^{2} + 4 y^{2} - (y z + 2 y^{2}) = z^{2} + 4 y^{2} - y z - 2 y^{2} = z^{2} + 2 y^{2} - y z$
