What two numbers multiply to 864 and add up to 70?

Here we answer the question: "What two numbers multiply to 864 and add up to 70?"

The answer to your question is:

16 and 54

Below we illustrate and prove that 16 and 54 multiply to 864 and add up to 70:

16 × 54 = 864
16 + 54 = 70

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

x² + 70x + 864 = 0

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

(x + 16 ) (x + 54)

To summarize, since 16 and 54 multiply to 864 and add up 70, you know that the following is true:

x² + 70x + 864 = (x + 16 ) (x + 54)
