What two numbers multiply to 486 and add up to -87?

Here we answer the question: "What two numbers multiply to 486 and add up to -87?"

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 -87:

-81 × -6 = 486
-81 + -6 = -87

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

x² - 87x + 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 -87, you know that the following is true:

x² - 87x + 486 = (x - 81 ) (x - 6)
