What two numbers multiply to 420 and add up to -67?

Here we answer the question: "What two numbers multiply to 420 and add up to -67?"

The answer to your question is:

-60 and -7

Below we illustrate and prove that -60 and -7 multiply to 420 and add up to -67:

-60 × -7 = 420
-60 + -7 = -67

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

x² - 67x + 420 = 0

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

(x - 60 ) (x - 7)

To summarize, since -60 and -7 multiply to 420 and add up -67, you know that the following is true:

x² - 67x + 420 = (x - 60 ) (x - 7)
