Here we answer the question: "What two numbers multiply to -513 and add up to -8?"
The answer to your question is:
-27 and 19
Below we illustrate and prove that -27 and 19 multiply to -513 and add up to -8:
-27 × 19 = -513
-27 + 19 = -8
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 8x - 513 = 0
If so, the solution to factor the quadratic equation above is:
(x - 27 ) (x + 19)
To summarize, since -27 and 19 multiply to -513 and add up -8, you know that the following is true:
x2 - 8x - 513 = (x - 27 ) (x + 19)
