What two numbers multiply to 90 and add up to -47?

Here we answer the question: "What two numbers multiply to 90 and add up to -47?"

The answer to your question is:

-45 and -2

Below we illustrate and prove that -45 and -2 multiply to 90 and add up to -47:

-45 × -2 = 90
-45 + -2 = -47

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

x² - 47x + 90 = 0

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

(x - 45 ) (x - 2)

To summarize, since -45 and -2 multiply to 90 and add up -47, you know that the following is true:

x² - 47x + 90 = (x - 45 ) (x - 2)
