What two numbers multiply to 56 and add up to -18?

Here we answer the question: "What two numbers multiply to 56 and add up to -18?"

The answer to your question is:

-14 and -4

Below we illustrate and prove that -14 and -4 multiply to 56 and add up to -18:

-14 × -4 = 56
-14 + -4 = -18

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

x² - 18x + 56 = 0

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

(x - 14 ) (x - 4)

To summarize, since -14 and -4 multiply to 56 and add up -18, you know that the following is true:

x² - 18x + 56 = (x - 14 ) (x - 4)
