What two numbers multiply to -318 and add up to 157?

Here we answer the question: "What two numbers multiply to -318 and add up to 157?"

The answer to your question is:

-2 and 159

Below we illustrate and prove that -2 and 159 multiply to -318 and add up to 157:

-2 × 159 = -318
-2 + 159 = 157

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

x² + 157x - 318 = 0

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

(x - 2 ) (x + 159)

To summarize, since -2 and 159 multiply to -318 and add up 157, you know that the following is true:

x² + 157x - 318 = (x - 2 ) (x + 159)
