What two numbers multiply to 864 and add up to -70?

Here we answer the question: "What two numbers multiply to 864 and add up to -70?"

The answer to your question is:

-54 and -16

Below we illustrate and prove that -54 and -16 multiply to 864 and add up to -70:

-54 × -16 = 864
-54 + -16 = -70

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

x² - 70x + 864 = 0

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

(x - 54 ) (x - 16)

To summarize, since -54 and -16 multiply to 864 and add up -70, you know that the following is true:

x² - 70x + 864 = (x - 54 ) (x - 16)
