What two numbers multiply to -270 and add up to -87?

Here we answer the question: "What two numbers multiply to -270 and add up to -87?"

The answer to your question is:

-90 and 3

Below we illustrate and prove that -90 and 3 multiply to -270 and add up to -87:

-90 × 3 = -270
-90 + 3 = -87

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

x² - 87x - 270 = 0

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

(x - 90 ) (x + 3)

To summarize, since -90 and 3 multiply to -270 and add up -87, you know that the following is true:

x² - 87x - 270 = (x - 90 ) (x + 3)
