What two numbers multiply to 160 and add up to -28?

Here we answer the question: "What two numbers multiply to 160 and add up to -28?"

The answer to your question is:

-20 and -8

Below we illustrate and prove that -20 and -8 multiply to 160 and add up to -28:

-20 × -8 = 160
-20 + -8 = -28

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

x² - 28x + 160 = 0

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

(x - 20 ) (x - 8)

To summarize, since -20 and -8 multiply to 160 and add up -28, you know that the following is true:

x² - 28x + 160 = (x - 20 ) (x - 8)
