What two numbers multiply to 178 and add up to 91?

Here we answer the question: "What two numbers multiply to 178 and add up to 91?"

The answer to your question is:

2 and 89

Below we illustrate and prove that 2 and 89 multiply to 178 and add up to 91:

2 × 89 = 178
2 + 89 = 91

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

x² + 91x + 178 = 0

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

(x + 2 ) (x + 89)

To summarize, since 2 and 89 multiply to 178 and add up 91, you know that the following is true:

x² + 91x + 178 = (x + 2 ) (x + 89)
