What two numbers multiply to 870 and add up to -151?

Here we answer the question: "What two numbers multiply to 870 and add up to -151?"

The answer to your question is:

-145 and -6

Below we illustrate and prove that -145 and -6 multiply to 870 and add up to -151:

-145 × -6 = 870
-145 + -6 = -151

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

x² - 151x + 870 = 0

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

(x - 145 ) (x - 6)

To summarize, since -145 and -6 multiply to 870 and add up -151, you know that the following is true:

x² - 151x + 870 = (x - 145 ) (x - 6)
