What two numbers multiply to -149 and add up to 148?

Here we answer the question: "What two numbers multiply to -149 and add up to 148?"

The answer to your question is:

-1 and 149

Below we illustrate and prove that -1 and 149 multiply to -149 and add up to 148:

-1 × 149 = -149
-1 + 149 = 148

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

x² + 148x - 149 = 0

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

(x - 1 ) (x + 149)

To summarize, since -1 and 149 multiply to -149 and add up 148, you know that the following is true:

x² + 148x - 149 = (x - 1 ) (x + 149)
