What two numbers multiply to -36 and add up to 5?

Here we answer the question: "What two numbers multiply to -36 and add up to 5?"

The answer to your question is:

-4 and 9

Below we illustrate and prove that -4 and 9 multiply to -36 and add up to 5:

-4 × 9 = -36
-4 + 9 = 5

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

x² + 5x - 36 = 0

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

(x - 4 ) (x + 9)

To summarize, since -4 and 9 multiply to -36 and add up 5, you know that the following is true:

x² + 5x - 36 = (x - 4 ) (x + 9)
