（1）化简求值：2x^2+14x+24分之x^2+16+8x,其中x=-6当x=3,y=-2,求x^2-(y-1)^2分之x^2-y^2乘以x^2+2yx+y^2分之（x-y)^2-1除以x^2+xy-x分之x^2-xy的值、怎么做,
网友回答
2x^2+14x+24分之x^2+16+8x,其中x=-6
=(x²+8x+16))/2(x²+7x+12)
=(x+4)²/2(x+3)(x+4)
=(x+4)/2(x+3)
=(-6+4)/2(-6+3)
=-2/(-6)
=1/3当x=3,y=-2,求x^2-(y-1)^2分之x^2-y^2乘以x^2+2yx+y^2分之（x-y)^2-1除以x^2+xy-x分之x^2-xy的
=x²-(x²-y²)/(y-1)²*(x-y)²/(x²+2xy+y²)-1/(x²+xy)-(x²-xy)/x
这个题目看不懂
分子和分母分不清
======以下答案可供参考======
供参考答案1:
2x^2+14x+24分之x^2+16+8x,其中x=-6
最后算出等于-189.5
供参考答案2:
x=-6(x^2+16+8x)/(2x^2+14x+24)
=(x+4)^2/2(x+4)(x+3)
=(x+4)/2(x+3)
=(-6+4)/2(-6+3)
=1/3x=3，y=-2
x^2=9,y^2=4,xy= -6,x+y=1,x-y=5
x^2-(x^2-y^2)/(y-1)^2*（x-y)^2/*（x+y)^2*(x^2+xy-x)/(x^2-xy)
=9-(9-4)/9*25/1*(9-6-3)/(9+6)
=9供参考答案3:
