What two numbers multiply to -700 and add up to 135?

Here we answer the question: "What two numbers multiply to -700 and add up to 135?"

The answer to your question is:

-5 and 140

Below we illustrate and prove that -5 and 140 multiply to -700 and add up to 135:

-5 × 140 = -700
-5 + 140 = 135

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

x² + 135x - 700 = 0

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

(x - 5 ) (x + 140)

To summarize, since -5 and 140 multiply to -700 and add up 135, you know that the following is true:

x² + 135x - 700 = (x - 5 ) (x + 140)
