(x+4)^2-16x^2
(x+4)^2-16x^2
(x+4)^2-16x^2
分解因式还是求解
你要算什么?
(4-3x)*(5x+4)
(x^2-4x)/x^2-8x+16
(16x^4+4x^2+x)/x=?
(x+2)(x-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3)(x+2)(x-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3)

通分:(1)2/x^2+x-2,1/x^2-2x-8(2)x/x^2-3x-4,1/x^2-8x+16
(x-2)/(x+2)-16/(x^2-4)=(x+2)/(x-2)
(x^2-16/x^2+8x+16) + (x/x-4)
先化简.在求值:(x+2/x²-2x-x-1/x²-4x+4)÷x²-16/x²+4x
3x/(x-2)-x/(x+2)÷2x/(x-4)化简3x/(x-2)-x/(x+2)÷2x/(x²-4)化简
10x+2(x+4)=8x+16
(x/x-2-x/x+2)/4x/x-2
(1)X-3/X-1+X²-2/(x-1)(X-7)=1+x-5/x-7 (2)2x-1/x+4-5=96/x²-16-1-3x/4-x
(x-2)(x+2)(x^4+4x^2+16)
(x-2)(x+2)(x^2+4)(x^4+16)
(x-2)(x^2+4)(x^4+16)(x+2)
(x^2 + 4x)(x^2 + 4x+8)+16
