Here we answer the question: "What two numbers multiply to 440 and add up to -63?"
The answer to your question is:
-55 and -8
Below we illustrate and prove that -55 and -8 multiply to 440 and add up to -63:
-55 × -8 = 440
-55 + -8 = -63
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 63x + 440 = 0
If so, the solution to factor the quadratic equation above is:
(x - 55 ) (x - 8)
To summarize, since -55 and -8 multiply to 440 and add up -63, you know that the following is true:
x2 - 63x + 440 = (x - 55 ) (x - 8)
