What two numbers multiply to 340 and add up to 89?

Here we answer the question: "What two numbers multiply to 340 and add up to 89?"

The answer to your question is:

4 and 85

Below we illustrate and prove that 4 and 85 multiply to 340 and add up to 89:

4 × 85 = 340
4 + 85 = 89

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

x² + 89x + 340 = 0

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

(x + 4 ) (x + 85)

To summarize, since 4 and 85 multiply to 340 and add up 89, you know that the following is true:

x² + 89x + 340 = (x + 4 ) (x + 85)
