What two numbers multiply to -70 and add up to -69?

Here we answer the question: "What two numbers multiply to -70 and add up to -69?"

The answer to your question is:

-70 and 1

Below we illustrate and prove that -70 and 1 multiply to -70 and add up to -69:

-70 × 1 = -70
-70 + 1 = -69

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

x² - 69x - 70 = 0

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

(x - 70 ) (x + 1)

To summarize, since -70 and 1 multiply to -70 and add up -69, you know that the following is true:

x² - 69x - 70 = (x - 70 ) (x + 1)
