What two numbers multiply to 980 and add up to -63?

Here we answer the question: "What two numbers multiply to 980 and add up to -63?"

The answer to your question is:

-35 and -28

Below we illustrate and prove that -35 and -28 multiply to 980 and add up to -63:

-35 × -28 = 980
-35 + -28 = -63

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

x² - 63x + 980 = 0

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

(x - 35 ) (x - 28)

To summarize, since -35 and -28 multiply to 980 and add up -63, you know that the following is true:

x² - 63x + 980 = (x - 35 ) (x - 28)
