What two numbers multiply to 690 and add up to -233?

Here we answer the question: "What two numbers multiply to 690 and add up to -233?"

The answer to your question is:

-230 and -3

Below we illustrate and prove that -230 and -3 multiply to 690 and add up to -233:

-230 × -3 = 690
-230 + -3 = -233

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

x² - 233x + 690 = 0

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

(x - 230 ) (x - 3)

To summarize, since -230 and -3 multiply to 690 and add up -233, you know that the following is true:

x² - 233x + 690 = (x - 230 ) (x - 3)
