What two numbers multiply to -314 and add up to 155?

Here we answer the question: "What two numbers multiply to -314 and add up to 155?"

The answer to your question is:

-2 and 157

Below we illustrate and prove that -2 and 157 multiply to -314 and add up to 155:

-2 × 157 = -314
-2 + 157 = 155

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

x² + 155x - 314 = 0

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

(x - 2 ) (x + 157)

To summarize, since -2 and 157 multiply to -314 and add up 155, you know that the following is true:

x² + 155x - 314 = (x - 2 ) (x + 157)
