Here we answer the question: "What two numbers multiply to -777 and add up to -16?"
The answer to your question is:
-37 and 21
Below we illustrate and prove that -37 and 21 multiply to -777 and add up to -16:
-37 × 21 = -777
-37 + 21 = -16
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 16x - 777 = 0
If so, the solution to factor the quadratic equation above is:
(x - 37 ) (x + 21)
To summarize, since -37 and 21 multiply to -777 and add up -16, you know that the following is true:
x2 - 16x - 777 = (x - 37 ) (x + 21)
