计算：[﹙ab-2b﹚²×﹙2a﹚²－﹙4ab﹚²]÷[16a×﹙ab﹚²]还有一题，把下列个多项式分解因式（m²+3）²-8（m²+3）+16还有一题，当y-x=5时，求x²-y²+5x+5y+2009的值
计算：[﹙ab-2b﹚²×﹙2a﹚²－﹙4ab﹚²]÷[16a×﹙ab﹚²]
还有一题，把下列个多项式分解因式
（m²+3）²-8（m²+3）+16
还有一题，当y-x=5时，求x²-y²+5x+5y+2009的值
计算：[﹙ab-2b﹚²×﹙2a﹚²－﹙4ab﹚²]÷[16a×﹙ab﹚²]还有一题，把下列个多项式分解因式（m²+3）²-8（m²+3）+16还有一题，当y-x=5时，求x²-y²+5x+5y+2009的值
：[﹙ab-2b﹚²×﹙2a﹚²－﹙4ab﹚²]÷[16a×﹙ab﹚²]
=[(a²b²-4ab²+4b²)×4a²-16a²b²]÷16a³b²
=(4a的4次方b²-16a³b²+16a²b²-16a²b²)÷16a³b²
=(4a的4次方b²-16a³b²)÷16a³b²
=a/4-1
