What two numbers multiply to -155 and add up to 154?

Here we answer the question: "What two numbers multiply to -155 and add up to 154?"

The answer to your question is:

-1 and 155

Below we illustrate and prove that -1 and 155 multiply to -155 and add up to 154:

-1 × 155 = -155
-1 + 155 = 154

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

x² + 154x - 155 = 0

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

(x - 1 ) (x + 155)

To summarize, since -1 and 155 multiply to -155 and add up 154, you know that the following is true:

x² + 154x - 155 = (x - 1 ) (x + 155)
