Here we answer the question: "What two numbers multiply to -455 and add up to -86?"
The answer to your question is:
-91 and 5
Below we illustrate and prove that -91 and 5 multiply to -455 and add up to -86:
-91 × 5 = -455
-91 + 5 = -86
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 86x - 455 = 0
If so, the solution to factor the quadratic equation above is:
(x - 91 ) (x + 5)
To summarize, since -91 and 5 multiply to -455 and add up -86, you know that the following is true:
x2 - 86x - 455 = (x - 91 ) (x + 5)
