the polynomial is

x^2 + 2x + 1

i am getting the zero is -1 by mid term splitting
but as it is a degree 2 polynomial it should have 2 zeroes what is the other zero and the process to find it.

You have to count each root with its multiplicity.

As \(\displaystyle x^2+2x+1=(x+1)^2\), the multiplicity of the root -1 is 2.
