What two numbers multiply to -539 and add up to 70?

Here we answer the question: "What two numbers multiply to -539 and add up to 70?"

The answer to your question is:

-7 and 77

Below we illustrate and prove that -7 and 77 multiply to -539 and add up to 70:

-7 × 77 = -539
-7 + 77 = 70

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

x² + 70x - 539 = 0

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

(x - 7 ) (x + 77)

To summarize, since -7 and 77 multiply to -539 and add up 70, you know that the following is true:

x² + 70x - 539 = (x - 7 ) (x + 77)
