Answer:

-6

Explanation:

First we need to factorize the given expression

2x^2 - 5x - 3,

2x^2 - 6x+x - 3

The two number that we are going to use to split -5x are -6 and 1

Hence the required two numbers are -6 and 1

Let p = -6

Let q = 1

p+q = -6 + 1 = -5

Take the product

p*q = -6 * 1

p*q = -6

hence the product is equal to -6
