What two numbers multiply to -158 and add up to 157?

Here we answer the question: "What two numbers multiply to -158 and add up to 157?"

The answer to your question is:

-1 and 158

Below we illustrate and prove that -1 and 158 multiply to -158 and add up to 157:

-1 × 158 = -158
-1 + 158 = 157

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

x² + 157x - 158 = 0

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

(x - 1 ) (x + 158)

To summarize, since -1 and 158 multiply to -158 and add up 157, you know that the following is true:

x² + 157x - 158 = (x - 1 ) (x + 158)
