What two numbers multiply to -290 and add up to 289?

Here we answer the question: "What two numbers multiply to -290 and add up to 289?"

The answer to your question is:

-1 and 290

Below we illustrate and prove that -1 and 290 multiply to -290 and add up to 289:

-1 × 290 = -290
-1 + 290 = 289

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

x² + 289x - 290 = 0

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

(x - 1 ) (x + 290)

To summarize, since -1 and 290 multiply to -290 and add up 289, you know that the following is true:

x² + 289x - 290 = (x - 1 ) (x + 290)
