p(1)=0
so, (x-1) is a zero
after this, u can divide (x-1) by the given polynomial by long division method.
the quotient u get can be divided into two by using splitting the middle term method. and u get 3 factors. done!

For x=1,
p(1)=2(1)^3+5(1)^2-5(1)-2=2+5-5-2=0
hence, zero of the polynomial is 1.
