Answer 1

Answer:

y²+12y+27 = (y+9)(y+3)

Step-by-step explanation:

It may be like this ,

Quadratic expression

y²+12y+27

Splitting the middle term, we get

= y²+9y+3y+27

= y(y+9)+3(y+9)

= (y+9)(y+3)

Therefore,

y²+12y+27 = (y+9)(y+3)

Answer 2

Answer:    y=-3x,-9,-3/x

Step-by-step explanation:

y square +12x +27

y square +3xy+9xy=27

y(y+3x) + 9(xy+3)

(y+3x)  (y+9)   (xy+3)

y=-3x,    y=-9     xy=-3

                         y=-3/x
