What two numbers multiply to -315 and add up to 26?

Here we answer the question: "What two numbers multiply to -315 and add up to 26?"

The answer to your question is:

-9 and 35

Below we illustrate and prove that -9 and 35 multiply to -315 and add up to 26:

-9 × 35 = -315
-9 + 35 = 26

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

x² + 26x - 315 = 0

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

(x - 9 ) (x + 35)

To summarize, since -9 and 35 multiply to -315 and add up 26, you know that the following is true:

x² + 26x - 315 = (x - 9 ) (x + 35)
