What two numbers multiply to -88 and add up to 87?




Here we answer the question: "What two numbers multiply to -88 and add up to 87?"

The answer to your question is:

-1 and 88


Below we illustrate and prove that -1 and 88 multiply to -88 and add up to 87:

-1 × 88 = -88
-1 + 88 = 87

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

x2 + 87x - 88 = 0

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

(x - 1 ) (x + 88)

To summarize, since -1 and 88 multiply to -88 and add up 87, you know that the following is true:

x2 + 87x - 88 = (x - 1 ) (x + 88)
