What two numbers multiply to 90 and add up to 19?

Here we answer the question: "What two numbers multiply to 90 and add up to 19?"

The answer to your question is:

9 and 10

Below we illustrate and prove that 9 and 10 multiply to 90 and add up to 19:

9 × 10 = 90
9 + 10 = 19

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

x² + 19x + 90 = 0

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

(x + 9 ) (x + 10)

To summarize, since 9 and 10 multiply to 90 and add up 19, you know that the following is true:

x² + 19x + 90 = (x + 9 ) (x + 10)
