What two numbers multiply to 310 and add up to -157?

Here we answer the question: "What two numbers multiply to 310 and add up to -157?"

The answer to your question is:

-155 and -2

Below we illustrate and prove that -155 and -2 multiply to 310 and add up to -157:

-155 × -2 = 310
-155 + -2 = -157

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

x² - 157x + 310 = 0

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

(x - 155 ) (x - 2)

To summarize, since -155 and -2 multiply to 310 and add up -157, you know that the following is true:

x² - 157x + 310 = (x - 155 ) (x - 2)
