What two numbers multiply to -30 and add up to -7?

Here we answer the question: "What two numbers multiply to -30 and add up to -7?"

The answer to your question is:

-10 and 3

Below we illustrate and prove that -10 and 3 multiply to -30 and add up to -7:

-10 × 3 = -30
-10 + 3 = -7

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

x² - 7x - 30 = 0

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

(x - 10 ) (x + 3)

To summarize, since -10 and 3 multiply to -30 and add up -7, you know that the following is true:

x² - 7x - 30 = (x - 10 ) (x + 3)
