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:

-2 and 5

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

-2 × 5 = -10
-2 + 5 = 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 - 2 ) (x + 5)

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

x² + 3x - 10 = (x - 2 ) (x + 5)
