What two numbers multiply to 86 and add up to -45?

Here we answer the question: "What two numbers multiply to 86 and add up to -45?"

The answer to your question is:

-43 and -2

Below we illustrate and prove that -43 and -2 multiply to 86 and add up to -45:

-43 × -2 = 86
-43 + -2 = -45

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

x² - 45x + 86 = 0

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

(x - 43 ) (x - 2)

To summarize, since -43 and -2 multiply to 86 and add up -45, you know that the following is true:

x² - 45x + 86 = (x - 43 ) (x - 2)
