What two numbers multiply to -628 and add up to -153?

Here we answer the question: "What two numbers multiply to -628 and add up to -153?"

The answer to your question is:

-157 and 4

Below we illustrate and prove that -157 and 4 multiply to -628 and add up to -153:

-157 × 4 = -628
-157 + 4 = -153

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

x² - 153x - 628 = 0

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

(x - 157 ) (x + 4)

To summarize, since -157 and 4 multiply to -628 and add up -153, you know that the following is true:

x² - 153x - 628 = (x - 157 ) (x + 4)
