9y^2 -12y +4,,,,,,,,,factors of 9(9-1, 3-3) factors of 4(4-1, 2-2),,, (+) third term means signs are the same, and factor multiples add,,,,(-) 2nd term means, signs are (-).
.
( 3y-2) (3y-2)
.
F = 3y*3y= 9y^2
.
O= 3y*-2 = -6y
.
I = 3y *-2 = -6y
.
L = -2*-2 = +4
.
combining middle terms ,,, 9y^2 -12y +4
.
