Here we answer the question: "What two numbers multiply to -752 and add up to -31?"
The answer to your question is:
-47 and 16
Below we illustrate and prove that -47 and 16 multiply to -752 and add up to -31:
-47 × 16 = -752
-47 + 16 = -31
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 31x - 752 = 0
If so, the solution to factor the quadratic equation above is:
(x - 47 ) (x + 16)
To summarize, since -47 and 16 multiply to -752 and add up -31, you know that the following is true:
x2 - 31x - 752 = (x - 47 ) (x + 16)
