What two numbers multiply to 690 and add up to -347?

Here we answer the question: "What two numbers multiply to 690 and add up to -347?"

The answer to your question is:

-345 and -2

Below we illustrate and prove that -345 and -2 multiply to 690 and add up to -347:

-345 × -2 = 690
-345 + -2 = -347

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

x² - 347x + 690 = 0

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

(x - 345 ) (x - 2)

To summarize, since -345 and -2 multiply to 690 and add up -347, you know that the following is true:

x² - 347x + 690 = (x - 345 ) (x - 2)
