What two numbers multiply to -350 and add up to 65?

Here we answer the question: "What two numbers multiply to -350 and add up to 65?"

The answer to your question is:

-5 and 70

Below we illustrate and prove that -5 and 70 multiply to -350 and add up to 65:

-5 × 70 = -350
-5 + 70 = 65

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

x² + 65x - 350 = 0

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

(x - 5 ) (x + 70)

To summarize, since -5 and 70 multiply to -350 and add up 65, you know that the following is true:

x² + 65x - 350 = (x - 5 ) (x + 70)
