Solution for (3-2y)(3-2y)+(3-2y)y=2 equation:


Simplifying
(3 + -2y)(3 + -2y) + (3 + -2y) * y = 2

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

Combine like terms: -6y + -6y = -12y
(9 + -12y + 4y2) + (3 + -2y) * y = 2

Reorder the terms for easier multiplication:
9 + -12y + 4y2 + y(3 + -2y) = 2
9 + -12y + 4y2 + (3 * y + -2y * y) = 2
9 + -12y + 4y2 + (3y + -2y2) = 2

Reorder the terms:
9 + -12y + 3y + 4y2 + -2y2 = 2

Combine like terms: -12y + 3y = -9y
9 + -9y + 4y2 + -2y2 = 2

Combine like terms: 4y2 + -2y2 = 2y2
9 + -9y + 2y2 = 2

Solving
9 + -9y + 2y2 = 2

Solving for variable 'y'.

Reorder the terms:
9 + -2 + -9y + 2y2 = 2 + -2
