    Answer:

    p(x)=x²+2x+7

    let us do the discriminant

    d=b²-4ac

    =2²-4(1)(7)

    =4-28

    =-24

    as the discriminant is in negative

    the roots are imaginary

    so,the given polynomial has no roots

    hope the answer helps u

    Answer:

    here , a=1 b=2 c=7

    (b)^2-4ac=D(discriminant)= (2)^2-4(1)(7)=4-28= -24

    Explanation: as we know that when D is less than 0. then the quadratic equation have no real root or zero. therefore as the given equation shows the same case therefore it have no zero or root.

    this is the solution of ur question hope this will help you. Also please mark my answer as brainliest.
