a) x³ - 2x² + x

= x(x² - 2x + 1)

=x(x-1)²

b)2x² +4x+2-2y²

=2(x² +2x+1-y²)

=2[(x²+2x+1)-y²]

=2[(x+1)²-y²]

=2(x+1-y)(x+1+y)

c)2xy-x²-y²+16

=-[(x²-2xy+y²)-4²]

=-[(x-y)²-4²]

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

1-2a+2bc+a²-b²-c²

=(a²-2a+1)-(b²-2bc+c²)

=(a-1)²-(b-c)²

=[(a-1)-(b-c)][(a-1)+(b-c)]

=(a-1-b+c)(a-1+b-c)
