Simplifying
(2y + 3)(2y + 3) = cy2 + dy + 9

Reorder the terms:
(3 + 2y)(2y + 3) = cy2 + dy + 9

Reorder the terms:
(3 + 2y)(3 + 2y) = cy2 + dy + 9

Multiply (3 + 2y) * (3 + 2y)
(3(3 + 2y) + 2y * (3 + 2y)) = cy2 + dy + 9
((3 * 3 + 2y * 3) + 2y * (3 + 2y)) = cy2 + dy + 9
((9 + 6y) + 2y * (3 + 2y)) = cy2 + dy + 9
(9 + 6y + (3 * 2y + 2y * 2y)) = cy2 + dy + 9
(9 + 6y + (6y + 4y2)) = cy2 + dy + 9

Combine like terms: 6y + 6y = 12y
(9 + 12y + 4y2) = cy2 + dy + 9

12y + 4y2 = 0 + cy2 + dy
12y + 4y2 = cy2 + dy

Solving
12y + 4y2 = cy2 + dy

Solving for variable 'y'.

Reorder the terms:
-1cy2 + -1dy + 12y + 4y2 = cy2 + dy + -1cy2 + -1dy

Reorder the terms:
-1cy2 + -1dy + 12y + 4y2 = cy2 + -1cy2 + dy + -1dy

Combine like terms: cy2 + -1cy2 = 0
-1cy2 + -1dy + 12y + 4y2 = 0 + dy + -1dy
-1cy2 + -1dy + 12y + 4y2 = dy + -1dy

Combine like terms: dy + -1dy = 0
-1cy2 + -1dy + 12y + 4y2 = 0

Factor out the Greatest Common Factor (GCF), 'y'.
