因式分解8a^3b^2+12ab^3c,75x^3y^5-35x^2y^4,1/4a^3b^2-2a^2b^3.

问题描述:

因式分解8a^3b^2+12ab^3c,75x^3y^5-35x^2y^4,1/4a^3b^2-2a^2b^3.

8a³b²+12ab³c
=4ab²(2a²+3c)

75x³y^5-35x²y⁴
=5x²y⁴(15xy-7)

1/4a³b²-2a²b³
=a²b²(a-8b)/4

如果不懂,请追问,祝学习愉快!

8a^3b^2+12ab^3c
=4ab^2(2a^2+3bc)
75x^3y^5-35x^2y^4
=5x^2y^4(15xy-7)
1/4a^3b^2-2a^2b^3
=1/4a^2b^2(a-8b)
