Here we answer the question: "What two numbers multiply to 668 and add up to -669?"

The answer to your question is:

-668 and -1

Below we illustrate and prove that -668 and -1 multiply to 668 and add up to -669:

-668 × -1 = 668
-668 + -1 = -669

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

x² - 669x + 668 = 0
