What two numbers multiply to 825 and add up to 70?

Here we answer the question: "What two numbers multiply to 825 and add up to 70?"

The answer to your question is:

15 and 55

Below we illustrate and prove that 15 and 55 multiply to 825 and add up to 70:

15 × 55 = 825
15 + 55 = 70

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

x² + 70x + 825 = 0

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

(x + 15 ) (x + 55)

To summarize, since 15 and 55 multiply to 825 and add up 70, you know that the following is true:

x² + 70x + 825 = (x + 15 ) (x + 55)
