What two numbers multiply to -438 and add up to -143?

Here we answer the question: "What two numbers multiply to -438 and add up to -143?"

The answer to your question is:

-146 and 3

Below we illustrate and prove that -146 and 3 multiply to -438 and add up to -143:

-146 × 3 = -438
-146 + 3 = -143

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

x² - 143x - 438 = 0

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

(x - 146 ) (x + 3)

To summarize, since -146 and 3 multiply to -438 and add up -143, you know that the following is true:

x² - 143x - 438 = (x - 146 ) (x + 3)
