What two numbers multiply to -30 and add up to -1?

Here we answer the question: "What two numbers multiply to -30 and add up to -1?"

The answer to your question is:

-6 and 5

Below we illustrate and prove that -6 and 5 multiply to -30 and add up to -1:

-6 × 5 = -30
-6 + 5 = -1

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

x² - 1x - 30 = 0

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

(x - 6 ) (x + 5)

To summarize, since -6 and 5 multiply to -30 and add up -1, you know that the following is true:

x² - 1x - 30 = (x - 6 ) (x + 5)
