What two numbers multiply to 86 and add up to 87?

Here we answer the question: "What two numbers multiply to 86 and add up to 87?"

The answer to your question is:

1 and 86

Below we illustrate and prove that 1 and 86 multiply to 86 and add up to 87:

1 × 86 = 86
1 + 86 = 87

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

x² + 87x + 86 = 0

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

(x + 1 ) (x + 86)

To summarize, since 1 and 86 multiply to 86 and add up 87, you know that the following is true:

x² + 87x + 86 = (x + 1 ) (x + 86)
