What two numbers multiply to -1000 and add up to 30?

Here we answer the question: "What two numbers multiply to -1000 and add up to 30?"

The answer to your question is:

-20 and 50

Below we illustrate and prove that -20 and 50 multiply to -1000 and add up to 30:

-20 × 50 = -1000
-20 + 50 = 30

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

x² + 30x - 1000 = 0

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

(x - 20 ) (x + 50)

To summarize, since -20 and 50 multiply to -1000 and add up 30, you know that the following is true:

x² + 30x - 1000 = (x - 20 ) (x + 50)
