Work Step by Step

First lets represent the first integer as n and the second consecutive integer as n+1. Then lets add the two integers: n+n+1=2n+1 Now lets equate this expression to the sum of these integers given to us in the problem. 2n+1=-15 (Subtract 1 to both sides) 2n=-16 (Divide both sides by 2) n=-8 So now that we know the first integer, lets add 1 to get to our next integer: -8+1=-7 Now multiply the two integers since the problem asks for the product: -7 $\times$-8 = 56 So the product is 56.
