What two numbers multiply to 780 and add up to 88?

Here we answer the question: "What two numbers multiply to 780 and add up to 88?"

The answer to your question is:

10 and 78

Below we illustrate and prove that 10 and 78 multiply to 780 and add up to 88:

10 × 78 = 780
10 + 78 = 88

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

x² + 88x + 780 = 0

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

(x + 10 ) (x + 78)

To summarize, since 10 and 78 multiply to 780 and add up 88, you know that the following is true:

x² + 88x + 780 = (x + 10 ) (x + 78)
