Paul creates the diagram to 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

5x and -4x

Step-by-step explanation:

To find out factors we need to multiply 4 and -5 that is -20

Now product is -20 and sum is +1

We need to find out two factors whose product is -20 and sum is +1

5 times -4 = -20

5 + (-4) = +1

So +1x can be written as +5x - 4x

can be written as
