What two numbers multiply to -310 and add up to 153?

Here we answer the question: "What two numbers multiply to -310 and add up to 153?"

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 153:

-2 × 155 = -310
-2 + 155 = 153

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

x² + 153x - 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 153, you know that the following is true:

x² + 153x - 310 = (x - 2 ) (x + 155)
