What two numbers multiply to -470 and add up to 469?

Here we answer the question: "What two numbers multiply to -470 and add up to 469?"

The answer to your question is:

-1 and 470

Below we illustrate and prove that -1 and 470 multiply to -470 and add up to 469:

-1 × 470 = -470
-1 + 470 = 469

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

x² + 469x - 470 = 0

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

(x - 1 ) (x + 470)

To summarize, since -1 and 470 multiply to -470 and add up 469, you know that the following is true:

x² + 469x - 470 = (x - 1 ) (x + 470)
