What two numbers multiply to -675 and add up to -30?

Here we answer the question: "What two numbers multiply to -675 and add up to -30?"

The answer to your question is:

-45 and 15

Below we illustrate and prove that -45 and 15 multiply to -675 and add up to -30:

-45 × 15 = -675
-45 + 15 = -30

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

x² - 30x - 675 = 0

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

(x - 45 ) (x + 15)

To summarize, since -45 and 15 multiply to -675 and add up -30, you know that the following is true:

x² - 30x - 675 = (x - 45 ) (x + 15)
