x3 - 2y2 - 3x3 + z4 if x = 3, y = 5, and z = -3. 
first gather and add the same numbers 
=x3 -3x3 - 2y2 + z4 = -2x3 - 2y2 + z4=-2*3^3 -2*5²+(-3)^4=-54-50+81=-13 


2x2 - 2z4 + y2 - x2 + z4 if x = -4, y = 3, and z = 2. 
=2x2 -x2 - 2z4 + z4 + y2 = x² -z^4 +y² = ( -4)² -2^4 +3²=16 -16 +9 = 9 

*****3b(b + 5)*****
