What two numbers multiply to 698 and add up to 699?

Here we answer the question: "What two numbers multiply to 698 and add up to 699?"

The answer to your question is:

1 and 698

Below we illustrate and prove that 1 and 698 multiply to 698 and add up to 699:

1 × 698 = 698
1 + 698 = 699

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

x² + 699x + 698 = 0

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

(x + 1 ) (x + 698)

To summarize, since 1 and 698 multiply to 698 and add up 699, you know that the following is true:

x² + 699x + 698 = (x + 1 ) (x + 698)
