What two numbers multiply to -148 and add up to 147?

Here we answer the question: "What two numbers multiply to -148 and add up to 147?"

The answer to your question is:

-1 and 148

Below we illustrate and prove that -1 and 148 multiply to -148 and add up to 147:

-1 × 148 = -148
-1 + 148 = 147

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

x² + 147x - 148 = 0

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

(x - 1 ) (x + 148)

To summarize, since -1 and 148 multiply to -148 and add up 147, you know that the following is true:

x² + 147x - 148 = (x - 1 ) (x + 148)
