Question

p(x)=xsquare+2x+1 find the zero of this polynomial​

Answer 1

formula for quadratic equations =$-b+-\sqrt{b^{2} -4ac} /2a$

where b is the coefficient of x and a is the  coefficient of x square and c is the last apply this formula you will get

  -2+-$\sqrt{2^{2}-4*1*1 }$/2*1

you will get -2+-0/2

which is -1 and -1 are your roots
