(y-2)^3 + 6(y-2)^2 + 12(y-2) + 8
Expanding the terms:
(y-2)^3 = (y-2)(y-2)(y-2)= (y^2 - 4y + 4)(y-2)= y^3 - 2y^2 - 4y^2 + 8y + 4y - 8= y^3 - 6y^2 + 12y - 8
6(y-2)^2 = 6(y^2 - 4y + 4)= 6y^2 - 24y + 24
12(y-2) = 12y - 24
Now, putting all the expanded terms together:
(y-2)^3 + 6(y-2)^2 + 12(y-2) + 8= y^3 - 6y^2 + 12y - 8 + 6y^2 - 24y + 24 + 12y - 24 + 8= y^3 + 12y
(y-2)^3 + 6(y-2)^2 + 12(y-2) + 8
Expanding the terms:
(y-2)^3 = (y-2)(y-2)(y-2)
= (y^2 - 4y + 4)(y-2)
= y^3 - 2y^2 - 4y^2 + 8y + 4y - 8
= y^3 - 6y^2 + 12y - 8
6(y-2)^2 = 6(y^2 - 4y + 4)
= 6y^2 - 24y + 24
12(y-2) = 12y - 24
Now, putting all the expanded terms together:
(y-2)^3 + 6(y-2)^2 + 12(y-2) + 8
= y^3 - 6y^2 + 12y - 8 + 6y^2 - 24y + 24 + 12y - 24 + 8
= y^3 + 12y
