What two numbers multiply to 825 and add up to -70?

Here we answer the question: "What two numbers multiply to 825 and add up to -70?"

The answer to your question is:

-55 and -15

Below we illustrate and prove that -55 and -15 multiply to 825 and add up to -70:

-55 × -15 = 825
-55 + -15 = -70

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

x² - 70x + 825 = 0

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

(x - 55 ) (x - 15)

To summarize, since -55 and -15 multiply to 825 and add up -70, you know that the following is true:

x² - 70x + 825 = (x - 55 ) (x - 15)
