What two numbers multiply to 628 and add up to -161?

Here we answer the question: "What two numbers multiply to 628 and add up to -161?"

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 -161:

-157 × -4 = 628
-157 + -4 = -161

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

x² - 161x + 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 -161, you know that the following is true:

x² - 161x + 628 = (x - 157 ) (x - 4)
