What two numbers multiply to 78 and add up to -29?

Here we answer the question: "What two numbers multiply to 78 and add up to -29?"

The answer to your question is:

-26 and -3

Below we illustrate and prove that -26 and -3 multiply to 78 and add up to -29:

-26 × -3 = 78
-26 + -3 = -29

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

x² - 29x + 78 = 0

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

(x - 26 ) (x - 3)

To summarize, since -26 and -3 multiply to 78 and add up -29, you know that the following is true:

x² - 29x + 78 = (x - 26 ) (x - 3)
