What two numbers multiply to -770 and add up to 67?

Here we answer the question: "What two numbers multiply to -770 and add up to 67?"

The answer to your question is:

-10 and 77

Below we illustrate and prove that -10 and 77 multiply to -770 and add up to 67:

-10 × 77 = -770
-10 + 77 = 67

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

x² + 67x - 770 = 0

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

(x - 10 ) (x + 77)

To summarize, since -10 and 77 multiply to -770 and add up 67, you know that the following is true:

x² + 67x - 770 = (x - 10 ) (x + 77)
