What two numbers multiply to -87 and add up to 26?

Here we answer the question: "What two numbers multiply to -87 and add up to 26?"

The answer to your question is:

-3 and 29

Below we illustrate and prove that -3 and 29 multiply to -87 and add up to 26:

-3 × 29 = -87
-3 + 29 = 26

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

x² + 26x - 87 = 0

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

(x - 3 ) (x + 29)

To summarize, since -3 and 29 multiply to -87 and add up 26, you know that the following is true:

x² + 26x - 87 = (x - 3 ) (x + 29)
