What two numbers multiply to 310 and add up to 157?

Here we answer the question: "What two numbers multiply to 310 and add up to 157?"

The answer to your question is:

2 and 155

Below we illustrate and prove that 2 and 155 multiply to 310 and add up to 157:

2 × 155 = 310
2 + 155 = 157

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

x² + 157x + 310 = 0

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

(x + 2 ) (x + 155)

To summarize, since 2 and 155 multiply to 310 and add up 157, you know that the following is true:

x² + 157x + 310 = (x + 2 ) (x + 155)
