when X=2
p(2)=2*2^3-13*2^2+17*2+2
= 16-52+34+2
= 52-52=0
when X=-2
p(-2)=2*(-2)^3-13*(-2)^2+17*(-2)+2
=-16-52-34+2
= -100

I) when X=(-15)
p(-15)=-15+15=0
ii) when X=(-12.5)
p(-12.5)=2*(-12.5)+25=0

given
X-2
Co.paring with X-a we get a=2
so. f(2)=2*2^3-3*2^2-17*2+30
=16-12-34+30
=0
since f(2)=0 (X-2) is factor
