What two numbers multiply to 770 and add up to 87?

Here we answer the question: "What two numbers multiply to 770 and add up to 87?"

The answer to your question is:

10 and 77

Below we illustrate and prove that 10 and 77 multiply to 770 and add up to 87:

10 × 77 = 770
10 + 77 = 87

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

x² + 87x + 770 = 0

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

(x + 10 ) (x + 77)

To summarize, since 10 and 77 multiply to 770 and add up 87, you know that the following is true:

x² + 87x + 770 = (x + 10 ) (x + 77)
