Your doing everything correctly
Answer:

Step-by-step explanation:
Given

Required
Fill in the gap to produce the product of linear expressions

Split to 2

Factorize the first bracket

Represent the _ with X

Factorize the second bracket

To result in a linear expression, then the following condition must be satisfied;

Subtract b from both sides


Multiply both sides by 5


Substitute -15 for X in 




The two linear expressions are
and 
Their product will result in 
<em>Hence, the constant is -15</em>
-2(2x-1)(x+3) = ((-2)2x - (-2)(-1))(x+3) = (-4x-2)(x+3)
