Answer:
1 and 7
Explanation:
The answer to your question is:
1 and 7
Below we illustrate and prove that 1 and 7 multiply to 7 and add up to 8:
1 × 7 = 7
1 + 7 = 8
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 8x + 7 = 0
If so, the solution to factor the quadratic equation above is:
(x + 1 ) (x + 7)
To summarize, since 1 and 7 multiply to 7 and add up 8, you know that the following is true:
x2 + 8x + 7 = (x + 1 ) (x + 7)
