What two numbers multiply to -40 and add up to 3?




Here we answer the question: "What two numbers multiply to -40 and add up to 3?"

The answer to your question is:

-5 and 8


Below we illustrate and prove that -5 and 8 multiply to -40 and add up to 3:

-5 × 8 = -40
-5 + 8 = 3

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

x2 + 3x - 40 = 0

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

(x - 5 ) (x + 8)

To summarize, since -5 and 8 multiply to -40 and add up 3, you know that the following is true:

x2 + 3x - 40 = (x - 5 ) (x + 8)
