    Simplifying y (2x + 3y) (2x + 3y)

    Multiply (2x + 3y) * (2x + 3y) y (2x * (2x + 3y) + 3y * (2x + 3y)) y ((2x * 2x + 3y * 2x) + 3y * (2x + 3y))

    Reorder the terms: y ((6xy + 4x2) + 3y * (2x + 3y)) y ((6xy + 4x2) + 3y * (2x + 3y)) y (6xy + 4x2 + (2x * 3y + 3y * 3y)) y (6xy + 4x2 + (6xy + 9y2))

    Reorder the terms: y (6xy + 6xy + 4x2 + 9y2)

    Combine like terms: 6xy + 6xy = 12xy y (12xy + 4x2 + 9y2) (12xy * y + 4x2 * y + 9y2 * y) (12xy2 + 4x2y + 9y3)
