Question

the sum of two consecutive integers is -15. what is the product of the two integers? please help!!!!

2 Answer


  • The only pair of consecutive integers that
    adds to  -15  is  -7  and  -8 .

           ( -7 ) x ( - 8 )  =  + 56 .

  • x + x +1 = -15
    2x +1 =-15
    2x=-16
    x = -8
    x +1 = 76

    -8 x -7 = 556

    56 is the product of the 2 consecutive numbers that add up to -15.
