What two numbers multiply to 90 and add up to 91?




Here we answer the question: "What two numbers multiply to 90 and add up to 91?"

The answer to your question is:

1 and 90


Below we illustrate and prove that 1 and 90 multiply to 90 and add up to 91:

1 × 90 = 90
1 + 90 = 91

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

x2 + 91x + 90 = 0

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

(x + 1 ) (x + 90)

To summarize, since 1 and 90 multiply to 90 and add up 91, you know that the following is true:

x2 + 91x + 90 = (x + 1 ) (x + 90)
