What two numbers multiply to 406 and add up to -65?

Here we answer the question: "What two numbers multiply to 406 and add up to -65?"

The answer to your question is:

-58 and -7

Below we illustrate and prove that -58 and -7 multiply to 406 and add up to -65:

-58 × -7 = 406
-58 + -7 = -65

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

x² - 65x + 406 = 0

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

(x - 58 ) (x - 7)

To summarize, since -58 and -7 multiply to 406 and add up -65, you know that the following is true:

x² - 65x + 406 = (x - 58 ) (x - 7)
