Here we answer the question: "What two numbers multiply to 806 and add up to -57?"
The answer to your question is:
-31 and -26
Below we illustrate and prove that -31 and -26 multiply to 806 and add up to -57:
-31 × -26 = 806
-31 + -26 = -57
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 57x + 806 = 0
If so, the solution to factor the quadratic equation above is:
(x - 31 ) (x - 26)
To summarize, since -31 and -26 multiply to 806 and add up -57, you know that the following is true:
x2 - 57x + 806 = (x - 31 ) (x - 26)
