What two numbers multiply to 672 and add up to -58?

Here we answer the question: "What two numbers multiply to 672 and add up to -58?"

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 -58:

-42 × -16 = 672
-42 + -16 = -58

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

x² - 58x + 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 -58, you know that the following is true:

x² - 58x + 672 = (x - 42 ) (x - 16)
