P(X)=9x^3-5x+20
P(1)=9(1)-5(1)+20
=4+20
=24
Therefore It is not a zero
P(1)=9(1)-5(1)+20
=4+20
=24
Therefore It is not a zero

hey friend here is your answer
we put x=1 in equation if cones equal to 0 then 1 is root of equation
hence
9×1-5×1+20
9-5+20
29-5
24
does not equal to 0
so 1 is not root of equation
