What two numbers multiply to -345 and add up to -64?

Here we answer the question: "What two numbers multiply to -345 and add up to -64?"

The answer to your question is:

-69 and 5

Below we illustrate and prove that -69 and 5 multiply to -345 and add up to -64:

-69 × 5 = -345
-69 + 5 = -64

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

x² - 64x - 345 = 0

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

(x - 69 ) (x + 5)

To summarize, since -69 and 5 multiply to -345 and add up -64, you know that the following is true:

x² - 64x - 345 = (x - 69 ) (x + 5)
