Here we answer the question: "What two numbers multiply to -69 and add up to 20?"
The answer to your question is:
-3 and 23
Below we illustrate and prove that -3 and 23 multiply to -69 and add up to 20:
-3 × 23 = -69
-3 + 23 = 20
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 20x - 69 = 0
If so, the solution to factor the quadratic equation above is:
(x - 3 ) (x + 23)
To summarize, since -3 and 23 multiply to -69 and add up 20, you know that the following is true:
x2 + 20x - 69 = (x - 3 ) (x + 23)
