Here we answer the question: "What two numbers multiply to -340 and add up to -63?"
The answer to your question is:
-68 and 5
Below we illustrate and prove that -68 and 5 multiply to -340 and add up to -63:
-68 × 5 = -340
-68 + 5 = -63
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 63x - 340 = 0
If so, the solution to factor the quadratic equation above is:
(x - 68 ) (x + 5)
To summarize, since -68 and 5 multiply to -340 and add up -63, you know that the following is true:
x2 - 63x - 340 = (x - 68 ) (x + 5)
