What two numbers multiply to 128 and add up to -36?

Here we answer the question: "What two numbers multiply to 128 and add up to -36?"

The answer to your question is:

-32 and -4

Below we illustrate and prove that -32 and -4 multiply to 128 and add up to -36:

-32 × -4 = 128
-32 + -4 = -36

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

x² - 36x + 128 = 0

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

(x - 32 ) (x - 4)

To summarize, since -32 and -4 multiply to 128 and add up -36, you know that the following is true:

x² - 36x + 128 = (x - 32 ) (x - 4)
