What two numbers multiply to -128 and add up to 62?

Here we answer the question: "What two numbers multiply to -128 and add up to 62?"

The answer to your question is:

-2 and 64

Below we illustrate and prove that -2 and 64 multiply to -128 and add up to 62:

-2 × 64 = -128
-2 + 64 = 62

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

x² + 62x - 128 = 0

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

(x - 2 ) (x + 64)

To summarize, since -2 and 64 multiply to -128 and add up 62, you know that the following is true:

x² + 62x - 128 = (x - 2 ) (x + 64)
