x^2+6x+5
CASE -I
x=(-1)
(-1)(-1)+6(-1)+5
1-6+5
6-6=0
hence,x=(-1) is the zero of the given polynomial.
CASE-II
x=(-5)
(-5)(-5)+6(-5)+5
25-30+5
30-30=0
hence,X=(-5) is the zero of the given polynomial.
CASE -I
x=(-1)
(-1)(-1)+6(-1)+5
1-6+5
6-6=0
hence,x=(-1) is the zero of the given polynomial.
CASE-II
x=(-5)
(-5)(-5)+6(-5)+5
25-30+5
30-30=0
hence,X=(-5) is the zero of the given polynomial.
