Question

Phân tích thành nhân tử:

\(x^2-x-2001\cdot2002\)

Answer 1

x²-x-2001.2002

=x²+2001x-2002x-2001.2002

=x.(x+2001)-2002.(x+2001)

=(x+2001)(x-2002)

Answer 2

=x^2-x-2001.2002

=x.(x+2001)-2002.(x+2001)

=(x+2001).(x-2002)

tick nha !!!

Answer 3

=x^2-2002x+2001x-2001*2002

=x(x-2002)+2001(x-2002)

=(x-2002)(x+2001)
