the factor of x^2 + 8x + 7 is:
(x+7)(x+1) 
all you should do is to find two numbers:
____ + ____ = 8
____ * _____ = 7 
and the numbers are 7 and 1 :)))
i hope this is helpful
have a nice day

To factorize a quadratic equation, you need two numbers that multiply to c, 7, and add to b, 8.
Two numbers that mutiply to 7 and add to 8 are 7 and 1.
x^2+7x+x+7
Now group them together:
x(x+7)+1(x+7)
Since (x+7) is common, you can take that as a common factor.

(x+1)(x+7)

Hope this helps :)
