Answer:
1. 2x²+x²y-xy²-2y²
2. 36x²+36x+8
Step-by-step explanation:
1. (x-y) x (xx2+xy+yx2)
↓
xx(xx2+xy+yx2)-yx(xx2+xy+yx2)
Multiply the second parentheses by each term from the first parentheses
xx(xx2+xy+yx2)
2x²+x²y+2xy
Distribute x through the parentheses
2x²+x²y+2xy-2xy-xy²-2y²
2x²+x²y-xy²-2y²
Since two opposites add up to zero,Remove them from the expression
Solution: 2x²+x²y-xy²-2y²
2. (3x+2) x (9xx2-6x+4)
3xx(9xx2-6xt4)+2(9xx2-6x+4)
3xx(9xx2-6x+4)
54x²-18x²+12x
Distribute 3x through the parentheses
54x²-18x²+12x+36x-12x+8
54x²-18x²+36x+8
Since two opposites add up to zero, Remove them from the expression
Solution: 36x²+ 36x+8
