Here we answer the question: "What two numbers multiply to 840 and add up to 62?"
The answer to your question is:
20 and 42
Below we illustrate and prove that 20 and 42 multiply to 840 and add up to 62:
20 × 42 = 840
20 + 42 = 62
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 62x + 840 = 0
If so, the solution to factor the quadratic equation above is:
(x + 20 ) (x + 42)
To summarize, since 20 and 42 multiply to 840 and add up 62, you know that the following is true:
x2 + 62x + 840 = (x + 20 ) (x + 42)
