What two numbers multiply to -696 and add up to 79?

Here we answer the question: "What two numbers multiply to -696 and add up to 79?"

The answer to your question is:

-8 and 87

Below we illustrate and prove that -8 and 87 multiply to -696 and add up to 79:

-8 × 87 = -696
-8 + 87 = 79

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

x² + 79x - 696 = 0

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

(x - 8 ) (x + 87)

To summarize, since -8 and 87 multiply to -696 and add up 79, you know that the following is true:

x² + 79x - 696 = (x - 8 ) (x + 87)
