What two numbers multiply to -636 and add up to 155?

Here we answer the question: "What two numbers multiply to -636 and add up to 155?"

The answer to your question is:

-4 and 159

Below we illustrate and prove that -4 and 159 multiply to -636 and add up to 155:

-4 × 159 = -636
-4 + 159 = 155

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

x² + 155x - 636 = 0

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

(x - 4 ) (x + 159)

To summarize, since -4 and 159 multiply to -636 and add up 155, you know that the following is true:

x² + 155x - 636 = (x - 4 ) (x + 159)
