What two numbers multiply to -10 and add up to -3?

Here we answer the question: "What two numbers multiply to -10 and add up to -3?"

The answer to your question is:

-5 and 2

Below we illustrate and prove that -5 and 2 multiply to -10 and add up to -3:

-5 × 2 = -10
-5 + 2 = -3

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

x² - 3x - 10 = 0

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

(x - 5 ) (x + 2)

To summarize, since -5 and 2 multiply to -10 and add up -3, you know that the following is true:

x² - 3x - 10 = (x - 5 ) (x + 2)
