Fill in the blank with a constant, so that the resulting expression can be factored as the product of two linear expressions: 2ab-6a+5b+___ Please include an explanation too!

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

Hence, the constant is -15

i think the answer is true
