One of the simplest ways to solve these types of questions by hit and trial method.
Put the value of the solution is given questions and equate to zero. Or if putting the value of options will give result 0. Then that will be a factor.
Here, x^2+7x^2+4x+8. ----->[A]
First put the x= (x+1=0, i.e x=-1)
Replace the value of x by -1 in euqation [A]
-1^2+7(-1)^2+4(-1) +8
1+7+ (-4) +8 =12 not equle to 0
Similary put other values and check which will give the value of 0.
That will be the factors of given equations.
I hope that you understood this.
Thanks!!1
