What two numbers multiply to 975 and add up to -64?

Here we answer the question: "What two numbers multiply to 975 and add up to -64?"

The answer to your question is:

-39 and -25

Below we illustrate and prove that -39 and -25 multiply to 975 and add up to -64:

-39 × -25 = 975
-39 + -25 = -64

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

x² - 64x + 975 = 0

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

(x - 39 ) (x - 25)

To summarize, since -39 and -25 multiply to 975 and add up -64, you know that the following is true:

x² - 64x + 975 = (x - 39 ) (x - 25)
