What two numbers multiply to 620 and add up to -312?

Here we answer the question: "What two numbers multiply to 620 and add up to -312?"

The answer to your question is:

-310 and -2

Below we illustrate and prove that -310 and -2 multiply to 620 and add up to -312:

-310 × -2 = 620
-310 + -2 = -312

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

x² - 312x + 620 = 0

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

(x - 310 ) (x - 2)

To summarize, since -310 and -2 multiply to 620 and add up -312, you know that the following is true:

x² - 312x + 620 = (x - 310 ) (x - 2)
