Question

几道简单的分解因式的题2x^2-2x+1/24(x-1)^2+4(x-1)+14a(x-y)+8b(y-x)^2(a^2

Answer 1

1.原式=1/2*(2x-1)^2

2.原式=(2(x-1)+1)^2

=(2x-1)^2

3.原式=4(x-y)*[a+2b(x-y)]

4.原式=(a-b)^2-c(a-b)

=(a-b)(a-b-c)

5.原式=24m^2*n^2-6m^4-12m^2*n^2-6n^4

=-6m^4+12m^2*n^2-6n^4

=-6(m^2-n^2)^2

=-6(m+n)^2*(m-n)^2

6.原式=x^(n-2)*(x^2+6x+9)

=x^(n-2)*(x+3)^2

本来因式分解没什么过程的.分出来就算.不过既然你要我还是尽量写了点
