If your full question is: Paul creates the diagram to help him factor 4x2 + x – 5 by using double grouping. His diagram is incomplete. Which terms should Paul write in squares M1 and M2? 5x and −4x –5x and 4x –2x and 10x 2x and −10x, then the answer is -
[tex]4x^2 + x - 5 = 4x^2 + 5x - 4x - 5[/tex]
Therefore, required solution is 5x and -4x.
