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:

-3 and 143

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

-3 × 143 = -429
-3 + 143 = 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 - 3 ) (x + 143)

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

x² + 140x - 429 = (x - 3 ) (x + 143)
