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:

-64 and 2

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

-64 × 2 = -128
-64 + 2 = -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 - 64 ) (x + 2)

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

x² - 62x - 128 = (x - 64 ) (x + 2)
