What two numbers multiply to 869 and add up to 90?

Here we answer the question: "What two numbers multiply to 869 and add up to 90?"

The answer to your question is:

11 and 79

Below we illustrate and prove that 11 and 79 multiply to 869 and add up to 90:

11 × 79 = 869
11 + 79 = 90

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

x² + 90x + 869 = 0

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

(x + 11 ) (x + 79)

To summarize, since 11 and 79 multiply to 869 and add up 90, you know that the following is true:

x² + 90x + 869 = (x + 11 ) (x + 79)
