What two numbers multiply to -447 and add up to 146?

Here we answer the question: "What two numbers multiply to -447 and add up to 146?"

The answer to your question is:

-3 and 149

Below we illustrate and prove that -3 and 149 multiply to -447 and add up to 146:

-3 × 149 = -447
-3 + 149 = 146

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

x² + 146x - 447 = 0

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

(x - 3 ) (x + 149)

To summarize, since -3 and 149 multiply to -447 and add up 146, you know that the following is true:

x² + 146x - 447 = (x - 3 ) (x + 149)
