What two numbers multiply to 630 and add up to 97?

Here we answer the question: "What two numbers multiply to 630 and add up to 97?"

The answer to your question is:

7 and 90

Below we illustrate and prove that 7 and 90 multiply to 630 and add up to 97:

7 × 90 = 630
7 + 90 = 97

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

x² + 97x + 630 = 0

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

(x + 7 ) (x + 90)

To summarize, since 7 and 90 multiply to 630 and add up 97, you know that the following is true:

x² + 97x + 630 = (x + 7 ) (x + 90)
