What two numbers multiply to 125 and add up to -30?

Here we answer the question: "What two numbers multiply to 125 and add up to -30?"

The answer to your question is:

-25 and -5

Below we illustrate and prove that -25 and -5 multiply to 125 and add up to -30:

-25 × -5 = 125
-25 + -5 = -30

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

x² - 30x + 125 = 0

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

(x - 25 ) (x - 5)

To summarize, since -25 and -5 multiply to 125 and add up -30, you know that the following is true:

x² - 30x + 125 = (x - 25 ) (x - 5)
