What two numbers multiply to 620 and add up to 312?

Here we answer the question: "What two numbers multiply to 620 and add up to 312?"

The answer to your question is:

2 and 310

Below we illustrate and prove that 2 and 310 multiply to 620 and add up to 312:

2 × 310 = 620
2 + 310 = 312

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

x² + 312x + 620 = 0

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

(x + 2 ) (x + 310)

To summarize, since 2 and 310 multiply to 620 and add up 312, you know that the following is true:

x² + 312x + 620 = (x + 2 ) (x + 310)
