6x²-11xy+3y²

2 -3

3 -1

=(2x-3y)(3x-y)

6(x+y)²-11(x+y)(x-y)+3(x-y)²

2 -3

3 -1

=(2x+2y-3x+3y)(3x+3y-x+y)

=(-x+5y)(2x+4y)

16 x^4-17x²+1

1 -1

16 -1

=(x^2-1)(16x^2-1)

=(x+1)(x-1)(4x+1)(4x-1)

9x的四次方-13x²y²+4y的四次方

1 -1

9 -4

=(x+y)(x-y)(3x-2y)(3x+2y)

5+7(a+1)-6(a+1)²

=-[6(a+1)²-7(a+1)-5]

2 1

3 -5

=-(2a+2+1)(3a+3-5)

=-(2a+3)(3a-2)
