    Answer:

    y^2+28y+196

    Step-by-step explanation:

    We are given that

    y^2+28y+..

    We have to fill in the number that makes the polynomial a perfect square quadratic.

    We know that

    (a+b)^2=a^2+2\times a\times b+b^2

    Using the formula

    Expand the expression

    (y)^2+2\times y\times 14+(14)^2

    (y+14)^2

    =y^2+28y+196
