What two numbers multiply to -70 and add up to -3?

Here we answer the question: "What two numbers multiply to -70 and add up to -3?"

The answer to your question is:

-10 and 7

Below we illustrate and prove that -10 and 7 multiply to -70 and add up to -3:

-10 × 7 = -70
-10 + 7 = -3

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

x² - 3x - 70 = 0

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

(x - 10 ) (x + 7)

To summarize, since -10 and 7 multiply to -70 and add up -3, you know that the following is true:

x² - 3x - 70 = (x - 10 ) (x + 7)
