(1):25X²-(X²+6)²=?(2):X^3-xy²+x²y-x²z 因式分解
(1):25X²-(X²+6)²=?(2):X^3-xy²+x²y-x²z 因式分解
(1):25X²-(X²+6)²=?(2):X^3-xy²+x²y-x²z 因式分解
1、(5x)²-(x²+6)²
=(5x+x²+6)(5x-x²-6)
=-(x²+5x+6)(x²-5x+6)
=-(x+2)(x+3)(x-2)(x-3)
2、x³-xy²+x²y-x²z
=x(x²-y²+xy-xz)
(1):25X²-(X²+6)²=(5X+X²+6)(5X-X²-6)
=-(X+6)(X-1)(X-2)(X-3)
(2):X^3-xy²+x²y-x²z
=x(x²-y²+xy-xz)
