What two numbers multiply to -672 and add up to -26?

Here we answer the question: "What two numbers multiply to -672 and add up to -26?"

The answer to your question is:

-42 and 16

Below we illustrate and prove that -42 and 16 multiply to -672 and add up to -26:

-42 × 16 = -672
-42 + 16 = -26

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

x² - 26x - 672 = 0

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

(x - 42 ) (x + 16)

To summarize, since -42 and 16 multiply to -672 and add up -26, you know that the following is true:

x² - 26x - 672 = (x - 42 ) (x + 16)
