1.x^3-5x^2y-24xy^2
=x*(x²-5xy-24y²）
=x（x-8)（x+3）
2.-2m^2+7m-3
= -（2m²-7m+3）
= -（2m-1）（m-3）
3 9x^4-82x+9
=(9x^2-1)(x^-9)
=(3x+1)(3x-1)(x+3)(x-3)
4 1/5x^2-3x+10
=1/5x^2-3x+10
=(1/5)*(x^2-15x+50)
=(1/5)(x-5)(x-10)
5 x^3-x^2-y^3+y^2
=x^3-y^3-（x²-y²）=(x-y)(x²+xy+y²)-（x-y）（x+y)
=(x-y)(x²+xy+y²-x-y)
6 x^2-6xy+9y^2-3x+9y
=（x-3y）² -3（x-3y）
=（x-3y）（x-3y-3）

2x^2y^3+x^2y^2/5x^3y^2-x^2y^2=?

=x²y²(2y+1)/x²y²(5x-1)
=(2y+1)/(5x-1)
