What two numbers multiply to -624 and add up to 152?

Here we answer the question: "What two numbers multiply to -624 and add up to 152?"

The answer to your question is:

-4 and 156

Below we illustrate and prove that -4 and 156 multiply to -624 and add up to 152:

-4 × 156 = -624
-4 + 156 = 152

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

x² + 152x - 624 = 0

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

(x - 4 ) (x + 156)

To summarize, since -4 and 156 multiply to -624 and add up 152, you know that the following is true:

x² + 152x - 624 = (x - 4 ) (x + 156)
