Question

Factorise 3y square+9y+6=?​

Answer 1

Answer:

Step-by-step explanation:

3y^2+9y+6

3y^2+6y+3y+6

3y(y+2)+3(y+2)

(y+2)(3y+3)

Answer 2

Step-by-step explanation:

3y^2+9y+6=0

divide by 3

y^2+3y+2=0

y^2+2y+1y+2=0

(y^2+2y) (1y+2)=0

y(y+2) 1(y+2) =0

(y+2) ( y+1)=0

y+2=0 y+1=0

y=0-2 y=0-1

=-2

y=-1

y=-2 or y=-1
