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:

-3 and 146

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

-3 × 146 = -438
-3 + 146 = 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 - 3 ) (x + 146)

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

x² + 143x - 438 = (x - 3 ) (x + 146)
