    Answer:

    8,8

    Step-by-step explanation:

    Given that, p(y)=5y^2+4

    let, p(y)=5y^2+4=0

    =>5y^2+4=0

    =>5y^2=-4

    =>y^2=-4/5

    =>y=-√(4/5) or +√(4/5)

    =>y=-2/√5 or +2/√5

    now, according to question it is given that to find the value of polynomial at

    y=-2/√5,2/√5

    so, consider y=-2/√5

    p(-2/√5)=5(-2/√5)^2+4 =5(4/5)+4 =4+4 =8

    p(2/√5)=5(2/√5)^2+4 =5(4/5)+4 =4+4 =8

    therefore,

    the value of the polynomial at 2/√5 is 8

    the value of the polynomial at -2/√5 is also 8.

    Hope this would be helpful for you
