What two numbers multiply to 688 and add up to -59?

Here we answer the question: "What two numbers multiply to 688 and add up to -59?"

The answer to your question is:

-43 and -16

Below we illustrate and prove that -43 and -16 multiply to 688 and add up to -59:

-43 × -16 = 688
-43 + -16 = -59

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

x² - 59x + 688 = 0

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

(x - 43 ) (x - 16)

To summarize, since -43 and -16 multiply to 688 and add up -59, you know that the following is true:

x² - 59x + 688 = (x - 43 ) (x - 16)
