What two numbers multiply to -429 and add up to -140?

Here we answer the question: "What two numbers multiply to -429 and add up to -140?"

The answer to your question is:

-143 and 3

Below we illustrate and prove that -143 and 3 multiply to -429 and add up to -140:

-143 × 3 = -429
-143 + 3 = -140

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

x² - 140x - 429 = 0

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

(x - 143 ) (x + 3)

To summarize, since -143 and 3 multiply to -429 and add up -140, you know that the following is true:

x² - 140x - 429 = (x - 143 ) (x + 3)
