(x- 2y)^2 -3x(x - 2y) I need a solution thank you!

  -2(x -2y)(x +y)

Step-by-step explanation:

Given:

  (x- 2y)^2 -3x(x - 2y)

Find:

  the factored form

Solution:

We notice that (x -2y) is a factor of both terms, so we can factor it out:

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

  = -2(x -2y)(x +y)
