What two numbers multiply to -316 and add up to 75?

Here we answer the question: "What two numbers multiply to -316 and add up to 75?"

The answer to your question is:

-4 and 79

Below we illustrate and prove that -4 and 79 multiply to -316 and add up to 75:

-4 × 79 = -316
-4 + 79 = 75

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

x² + 75x - 316 = 0

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

(x - 4 ) (x + 79)

To summarize, since -4 and 79 multiply to -316 and add up 75, you know that the following is true:

x² + 75x - 316 = (x - 4 ) (x + 79)
