What two numbers multiply to 620 and add up to -159?

Here we answer the question: "What two numbers multiply to 620 and add up to -159?"

The answer to your question is:

-155 and -4

Below we illustrate and prove that -155 and -4 multiply to 620 and add up to -159:

-155 × -4 = 620
-155 + -4 = -159

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

x² - 159x + 620 = 0

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

(x - 155 ) (x - 4)

To summarize, since -155 and -4 multiply to 620 and add up -159, you know that the following is true:

x² - 159x + 620 = (x - 155 ) (x - 4)
