Here we answer the question: "What two numbers multiply to -343 and add up to -42?"

The answer to your question is:

-49 and 7

Below we illustrate and prove that -49 and 7 multiply to -343 and add up to -42:

-49 × 7 = -343
-49 + 7 = -42

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

x² - 42x - 343 = 0

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

(x - 49 ) (x + 7)

To summarize, since -49 and 7 multiply to -343 and add up -42, you know that the following is true:

x² - 42x - 343 = (x - 49 ) (x + 7)
