What two numbers multiply to -486 and add up to -75?

Here we answer the question: "What two numbers multiply to -486 and add up to -75?"

The answer to your question is:

-81 and 6

Below we illustrate and prove that -81 and 6 multiply to -486 and add up to -75:

-81 × 6 = -486
-81 + 6 = -75

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

x² - 75x - 486 = 0

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

(x - 81 ) (x + 6)

To summarize, since -81 and 6 multiply to -486 and add up -75, you know that the following is true:

x² - 75x - 486 = (x - 81 ) (x + 6)
