Easy
set to zero
those are the roots or xintersepts
(x+1)(x+4)(x-7)=0
x+1=0
x=-1
x+4=0
x=-4
x-7=0
x=7
xints are (-4,0) (-1,0) (7,0)
1 3/7 ~ One and three sevenths
Step-by-step explanation:
u should attach the picture of the question because its difficult to identify where x is located
kindly attach the picture
