What two numbers multiply to 780 and add up to -67?

Here we answer the question: "What two numbers multiply to 780 and add up to -67?"

The answer to your question is:

-52 and -15

Below we illustrate and prove that -52 and -15 multiply to 780 and add up to -67:

-52 × -15 = 780
-52 + -15 = -67

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

x² - 67x + 780 = 0

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

(x - 52 ) (x - 15)

To summarize, since -52 and -15 multiply to 780 and add up -67, you know that the following is true:

x² - 67x + 780 = (x - 52 ) (x - 15)
