What two numbers multiply to 858 and add up to 89?

Here we answer the question: "What two numbers multiply to 858 and add up to 89?"

The answer to your question is:

11 and 78

Below we illustrate and prove that 11 and 78 multiply to 858 and add up to 89:

11 × 78 = 858
11 + 78 = 89

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

x² + 89x + 858 = 0

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

(x + 11 ) (x + 78)

To summarize, since 11 and 78 multiply to 858 and add up 89, you know that the following is true:

x² + 89x + 858 = (x + 11 ) (x + 78)
