Question

Complete the square. Fill in the number that makes the polynomial a perfect-square quadratic. y2 + 28y +

Answer 1

`y^2+28y+196`

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* a* b+b^2`

Using the formula

Expand the expression

`(y)^2+2* y* 14+(14)^2`

`(y+14)^2`

`=y^2+28y+196`
