What two numbers multiply to 420 and add up to -76?

Here we answer the question: "What two numbers multiply to 420 and add up to -76?"

The answer to your question is:

-70 and -6

Below we illustrate and prove that -70 and -6 multiply to 420 and add up to -76:

-70 × -6 = 420
-70 + -6 = -76

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

x² - 76x + 420 = 0

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

(x - 70 ) (x - 6)

To summarize, since -70 and -6 multiply to 420 and add up -76, you know that the following is true:

x² - 76x + 420 = (x - 70 ) (x - 6)
