What two numbers multiply to -150 and add up to 149?

Here we answer the question: "What two numbers multiply to -150 and add up to 149?"

The answer to your question is:

-1 and 150

Below we illustrate and prove that -1 and 150 multiply to -150 and add up to 149:

-1 × 150 = -150
-1 + 150 = 149

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

x² + 149x - 150 = 0

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

(x - 1 ) (x + 150)

To summarize, since -1 and 150 multiply to -150 and add up 149, you know that the following is true:

x² + 149x - 150 = (x - 1 ) (x + 150)
