What two numbers multiply to -513 and add up to 48?




Here we answer the question: "What two numbers multiply to -513 and add up to 48?"

The answer to your question is:

-9 and 57


Below we illustrate and prove that -9 and 57 multiply to -513 and add up to 48:

-9 × 57 = -513
-9 + 57 = 48

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x2 + 48x - 513 = 0

If so, the solution to factor the quadratic equation above is:

(x - 9 ) (x + 57)

To summarize, since -9 and 57 multiply to -513 and add up 48, you know that the following is true:

x2 + 48x - 513 = (x - 9 ) (x + 57)
