Solution for (y-9)(y+3)(y+3)= equation:


Simplifying
(y + -9)(y + 3)(y + 3) = 0

Reorder the terms:
(-9 + y)(y + 3)(y + 3) = 0

Reorder the terms:
(-9 + y)(3 + y)(y + 3) = 0

Reorder the terms:
(-9 + y)(3 + y)(3 + y) = 0

Multiply (-9 + y) * (3 + y)
(-9(3 + y) + y(3 + y))(3 + y) = 0
((3 * -9 + y * -9) + y(3 + y))(3 + y) = 0
((-27 + -9y) + y(3 + y))(3 + y) = 0
(-27 + -9y + (3 * y + y * y))(3 + y) = 0
(-27 + -9y + (3y + y2))(3 + y) = 0

Combine like terms: -9y + 3y = -6y
(-27 + -6y + y2)(3 + y) = 0

Multiply (-27 + -6y + y2) * (3 + y)
(-27(3 + y) + -6y * (3 + y) + y2(3 + y)) = 0
((3 * -27 + y * -27) + -6y * (3 + y) + y2(3 + y)) = 0
((-81 + -27y) + -6y * (3 + y) + y2(3 + y)) = 0
(-81 + -27y + (3 * -6y + y * -6y) + y2(3 + y)) = 0
(-81 + -27y + (-18y + -6y2) + y2(3 + y)) = 0
(-81 + -27y + -18y + -6y2 + (3 * y2 + y * y2)) = 0
(-81 + -27y + -18y + -6y2 + (3y2 + y3)) = 0

Combine like terms: -27y + -18y = -45y
(-81 + -45y + -6y2 + 3y2 + y3) = 0

Combine like terms: -6y2 + 3y2 = -3y2
(-81 + -45y + -3y2 + y3) = 0

Solving
-81 + -45y + -3y2 + y3 = 0

Solving for variable 'y'.
