What two numbers multiply to -42 and add up to -11?

Here we answer the question: "What two numbers multiply to -42 and add up to -11?"

The answer to your question is:

-14 and 3

Below we illustrate and prove that -14 and 3 multiply to -42 and add up to -11:

-14 × 3 = -42
-14 + 3 = -11

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

x² - 11x - 42 = 0

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

(x - 14 ) (x + 3)

To summarize, since -14 and 3 multiply to -42 and add up -11, you know that the following is true:

x² - 11x - 42 = (x - 14 ) (x + 3)
