What two numbers multiply to 658 and add up to -61?

Here we answer the question: "What two numbers multiply to 658 and add up to -61?"

The answer to your question is:

-47 and -14

Below we illustrate and prove that -47 and -14 multiply to 658 and add up to -61:

-47 × -14 = 658
-47 + -14 = -61

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

x² - 61x + 658 = 0

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

(x - 47 ) (x - 14)

To summarize, since -47 and -14 multiply to 658 and add up -61, you know that the following is true:

x² - 61x + 658 = (x - 47 ) (x - 14)
