Here we answer the question: "What two numbers multiply to -845 and add up to -52?"
The answer to your question is:
-65 and 13
Below we illustrate and prove that -65 and 13 multiply to -845 and add up to -52:
-65 × 13 = -845
-65 + 13 = -52
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 52x - 845 = 0
If so, the solution to factor the quadratic equation above is:
(x - 65 ) (x + 13)
To summarize, since -65 and 13 multiply to -845 and add up -52, you know that the following is true:
x2 - 52x - 845 = (x - 65 ) (x + 13)
