What two numbers multiply to -456 and add up to 149?

Here we answer the question: "What two numbers multiply to -456 and add up to 149?"

The answer to your question is:

-3 and 152

Below we illustrate and prove that -3 and 152 multiply to -456 and add up to 149:

-3 × 152 = -456
-3 + 152 = 149

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

x² + 149x - 456 = 0

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

(x - 3 ) (x + 152)

To summarize, since -3 and 152 multiply to -456 and add up 149, you know that the following is true:

x² + 149x - 456 = (x - 3 ) (x + 152)
