Here we answer the question: "What two numbers multiply to -792 and add up to -61?"
The answer to your question is:
-72 and 11
Below we illustrate and prove that -72 and 11 multiply to -792 and add up to -61:
-72 × 11 = -792
-72 + 11 = -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 - 72 ) (x + 11)
To summarize, since -72 and 11 multiply to -792 and add up -61, you know that the following is true:
x2 - 61x - 792 = (x - 72 ) (x + 11)
