What two numbers multiply to -665 and add up to 16?

Here we answer the question: "What two numbers multiply to -665 and add up to 16?"

The answer to your question is:

-19 and 35

Below we illustrate and prove that -19 and 35 multiply to -665 and add up to 16:

-19 × 35 = -665
-19 + 35 = 16

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

x² + 16x - 665 = 0

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

(x - 19 ) (x + 35)

To summarize, since -19 and 35 multiply to -665 and add up 16, you know that the following is true:

x² + 16x - 665 = (x - 19 ) (x + 35)
