What two numbers multiply to -430 and add up to 213?

Here we answer the question: "What two numbers multiply to -430 and add up to 213?"

The answer to your question is:

-2 and 215

Below we illustrate and prove that -2 and 215 multiply to -430 and add up to 213:

-2 × 215 = -430
-2 + 215 = 213

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

x² + 213x - 430 = 0

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

(x - 2 ) (x + 215)

To summarize, since -2 and 215 multiply to -430 and add up 213, you know that the following is true:

x² + 213x - 430 = (x - 2 ) (x + 215)
