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

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

The answer to your question is:

-157 and -1

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

-157 × -1 = 157
-157 + -1 = -158

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

x² - 158x + 157 = 0

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

(x - 157 ) (x - 1)

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

x² - 158x + 157 = (x - 157 ) (x - 1)
