Here we answer the question: "What two numbers multiply to -690 and add up to -343?"

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 -343:

-345 × 2 = -690
-345 + 2 = -343

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

x² - 343x - 690 = 0
