解下列方程或不等式1.(x-3)(-x-3)-(x-2)²+2x(x-3)=52.(x+3)(x-7)+8>(x+5)(x-1)
解下列方程或不等式
1.(x-3)(-x-3)-(x-2)²+2x(x-3)=5
2.(x+3)(x-7)+8>(x+5)(x-1)

解下列方程或不等式1.(x-3)(-x-3)-(x-2)²+2x(x-3)=52.(x+3)(x-7)+8>(x+5)(x-1)
1、(x-3)(-x-3)-(x-2)²+2x(x-3)
=-x²+9-x²+4x-4+2x²-6x
=-2x+5
=5
X=0
2、(x+3)(x-7)+8>(x+5)(x-1)
x²-4x-21+8>x²+4x-5
8>8x
1>X
