What two numbers multiply to 630 and add up to -97?

Here we answer the question: "What two numbers multiply to 630 and add up to -97?"

The answer to your question is:

-90 and -7

Below we illustrate and prove that -90 and -7 multiply to 630 and add up to -97:

-90 × -7 = 630
-90 + -7 = -97

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

x² - 97x + 630 = 0

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

(x - 90 ) (x - 7)

To summarize, since -90 and -7 multiply to 630 and add up -97, you know that the following is true:

x² - 97x + 630 = (x - 90 ) (x - 7)
