What two numbers multiply to 580 and add up to 149?

Here we answer the question: "What two numbers multiply to 580 and add up to 149?"

The answer to your question is:

4 and 145

Below we illustrate and prove that 4 and 145 multiply to 580 and add up to 149:

4 × 145 = 580
4 + 145 = 149

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

x² + 149x + 580 = 0

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

(x + 4 ) (x + 145)

To summarize, since 4 and 145 multiply to 580 and add up 149, you know that the following is true:

x² + 149x + 580 = (x + 4 ) (x + 145)
