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:

-3 and 90

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

-3 × 90 = -270
-3 + 90 = 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 - 3 ) (x + 90)

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

x² + 87x - 270 = (x - 3 ) (x + 90)
