因式分解的简单应用(a²-64)÷(a-8)(3x²y³+6x²y³)÷(x+2Y)(-9M²+4N²)÷(3m+2n)因式分解的

因式分解的简单应用 (a²-64)÷(a-8) (3x²y³+6x²y³)÷(x+2Y)(-9M²+4N²)÷(3m+2n)
因式分解的简单应用 (a²-64)÷(a-8) (3x²y³+6x²y³)÷(x+2Y)
(-9M²+4N²)÷(3m+2n)

因式分解的简单应用 (a²-64)÷(a-8) (3x²y³+6x²y³)÷(x+2Y)(-9M²+4N²)÷(3m+2n)
(a²-64)÷(a-8)
=(a-8)(a+8)÷(a-8)
=a+8
(3x²y³+6x²y³)÷(x+2Y)
=3xy(x+2y)÷(x+2y)
=3xy
(-9M²+4N²)÷(3m+2n)
=(-3m+2n)(3m+2n)÷(3m+2n)
=-3m+2n
