Here we answer the question: "What two numbers multiply to -792 and add up to 61?"
The answer to your question is:
-11 and 72
Below we illustrate and prove that -11 and 72 multiply to -792 and add up to 61:
-11 × 72 = -792
-11 + 72 = 61
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 61x - 792 = 0
If so, the solution to factor the quadratic equation above is:
(x - 11 ) (x + 72)
To summarize, since -11 and 72 multiply to -792 and add up 61, you know that the following is true:
x2 + 61x - 792 = (x - 11 ) (x + 72)
