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:

2 and 345

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

2 × 345 = 690
2 + 345 = 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 + 2 ) (x + 345)

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

x² + 347x + 690 = (x + 2 ) (x + 345)
