I am thinking of three consecutive negative numbers. If I multiply the first with the second and then subtract three times the third, the result is 57. What are the numbers? I need to know the correct algebra equation as well to get the numbers. Thanks.© BrainMass Inc. brainmass.com October 16, 2018, 9:25 pm ad1c9bdddf
Let the smallest number be x, then its consecutive numbers are x + 1 and x = 2
The equation is ...
