What two numbers multiply to -690 and add up to -133?

Here we answer the question: "What two numbers multiply to -690 and add up to -133?"

The answer to your question is:

-138 and 5

Below we illustrate and prove that -138 and 5 multiply to -690 and add up to -133:

-138 × 5 = -690
-138 + 5 = -133

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

x² - 133x - 690 = 0

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

(x - 138 ) (x + 5)

To summarize, since -138 and 5 multiply to -690 and add up -133, you know that the following is true:

x² - 133x - 690 = (x - 138 ) (x + 5)
