What two numbers multiply to -702 and add up to 69?




Here we answer the question: "What two numbers multiply to -702 and add up to 69?"

The answer to your question is:

-9 and 78


Below we illustrate and prove that -9 and 78 multiply to -702 and add up to 69:

-9 × 78 = -702
-9 + 78 = 69

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

x2 + 69x - 702 = 0

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

(x - 9 ) (x + 78)

To summarize, since -9 and 78 multiply to -702 and add up 69, you know that the following is true:

x2 + 69x - 702 = (x - 9 ) (x + 78)
