What two numbers multiply to 1000 and add up to -70?

Here we answer the question: "What two numbers multiply to 1000 and add up to -70?"

The answer to your question is:

-50 and -20

Below we illustrate and prove that -50 and -20 multiply to 1000 and add up to -70:

-50 × -20 = 1000
-50 + -20 = -70

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

x² - 70x + 1000 = 0

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

(x - 50 ) (x - 20)

To summarize, since -50 and -20 multiply to 1000 and add up -70, you know that the following is true:

x² - 70x + 1000 = (x - 50 ) (x - 20)
