What two numbers multiply to -770 and add up to 149?

Here we answer the question: "What two numbers multiply to -770 and add up to 149?"

The answer to your question is:

-5 and 154

Below we illustrate and prove that -5 and 154 multiply to -770 and add up to 149:

-5 × 154 = -770
-5 + 154 = 149

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

x² + 149x - 770 = 0

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

(x - 5 ) (x + 154)

To summarize, since -5 and 154 multiply to -770 and add up 149, you know that the following is true:

x² + 149x - 770 = (x - 5 ) (x + 154)
